| In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: finish active block group cleanup if call_zone_finish() fails
do_zone_finish() clears BLOCK_GROUP_FLAG_ZONE_IS_ACTIVE before finishing
the zones. If call_zone_finish() then fails it returned early, leaving the
now inactive block group on fs_info->zone_active_bgs, leaking its
reference, the BTRFS_FS_NEED_ZONE_FINISH waiters are never woken, and as
its alloc_offset equals the zone capacity btrfs_zone_finish_one_bg() keeps
selecting it, spinning btrfs_zoned_activate_one_bg().
Fall through to the cleanup on failure too and return the error, but keep
the block group read-only as its zones are left inconsistent. |
| In the Linux kernel, the following vulnerability has been resolved:
sunvdc: unmap LDC cookies when the descriptor send fails
__send_request() maps the request's pages into the LDC channel's map
table (ldc_map_sg()), fills in the descriptor and marks it
VIO_DESC_READY before ringing the doorbell via __vdc_tx_trigger().
When the trigger fails, the error path only prints a message: the
descriptor stays READY and the cookies are never unmapped. The
mapping is normally released in vdc_end_one() when the peer completes
the descriptor - but a descriptor whose doorbell was never sent will
never complete, and since dr->prod is not advanced on failure, the
reset path (vdc_requeue_inflight(), which walks [cons, prod)) never
visits it either. The map table entries are leaked permanently.
Since commit a11f6ca9aef9 ("sunvdc: Do not spin in an infinite loop
when vio_ldc_send() returns EAGAIN") trigger failures occur in
practice under load, so every resulting I/O error also leaks one
request's worth of entries from the fixed-size (8192 entries per
channel) map table. Because the allocator hands out contiguous
ranges, fragmentation makes large multi-segment requests fail first
as the table drains, until ldc_map_sg() fails permanently and the
disk is dead until reboot.
It also makes any retry-based recovery unusable: requeuing the
request on -EAGAIN remaps the pages on every attempt, overwriting
desc->cookies and orphaning the previous mapping, so the table
drains at the retry rate. This is the memory exhaustion observed
when the requeue approach was first tested in October 2025.
Roll back on failure: unmap the cookies, mark the descriptor FREE
again and clear the request entry. If the trigger failed with
-ENOTCONN, __vdc_tx_trigger() has already reset the port, which
tears down and reallocates both the dring and the LDC channel
including its map table - nothing to roll back, and the stale
descriptor must not be touched. |
| Improper Exposure of Resource to Wrong Sphere in the host file helper (gofer) in Google gVisor prior to commit 573a9e73cf844f on Linux platforms with CUSE enabled allows a local attacker with container image deployment privileges to achieve root code execution on the host system. By including a /dev/cuse character device node in a container image, opening the device passes through to the host, allowing the sandboxed attacker to register a host device and exploit CUSE unrestricted ioctl handling to overwrite root udev helper memory. |
| In the Linux kernel, the following vulnerability has been resolved:
s390/crypto: Map EBUSY to EIO when key conversion fails repeatedly
When hardware persistently returns -EBUSY after exhausting retries,
the error propagates to crypto_finalize_*_request(). The crypto API's
completion wrapper treats -EBUSY as a queueing status and swallows it,
preventing the completion callback from firing. This causes callers
using crypto_wait_req() to block indefinitely.
Translate persistent -EBUSY to -EIO after retry exhaustion to ensure
proper error propagation and callback invocation. |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: mediatek: paris: bypass pinctrl GPIO layer in set GPIO direction
pinctrl_gpio_direction_input() / pinctrl_gpio_direction_output() take
the pinctrl mutex. This causes a gpiochip operations to need to sleep.
Worse yet, the .can_sleep field in the gpiochip is not set. This causes
the shared GPIO proxy to trip over, as it uses gpiod_cansleep() to check
whether it can use a spinlock or needs a mutex. In this case, it ends
up taking a spinlock, then calls pinctrl_gpio_direction_output(), which
takes a mutex. This causes a huge warning.
While this class of Mediatek hardware does not have separate clear/set
registers, the pinctrl context has a spinlock that is taken whenever
a register read-modify-write is done. Also, once the GPIO function is
selected / muxed in, further GPIO operations do not involve pinctrl
operations or state. The GPIO direction and level values do not require
toggling the pinmux or any other pin config options.
Switch to directly calling mtk_pinmux_gpio_set_direction() in the GPIO
set direction callbacks to avoid taking the pinctrl mutex. Drop the
.gpio_set_direction field in mtk_pmxops to signal we are no longer using
the pinctrl GPIO layer for setting the direction. |
| When implementing the JavaScript interface, Foxit PDF Editor/Reader did not perform the attribute authorization checks required by the specification. As a result, a trusted malicious PDF could potentially access sensitive content from other documents within the same process and transmit it externally. |
| Dark Reader is an accessibility browser extension that makes web pages colors dark. Prior to 4.9.126, a website can cause the browser extension's image inversion pipeline to request an unauthenticated icon-like bitmap from a locally running web server when the resource uses a known public-like HTTPS URL and is detected as requiring inversion. This behavior can cross the website-to-local-network boundary and disclose limited information associated with the requested resource. The darkreader npm package used for website integration is not affected. This issue is fixed in version 4.9.126 for Firefox and version 4.9.128 for other browsers. |
| The Z80Ultra (NX741J) product contains a vulnerability where non-privileged programs can retrieve the Wi-Fi MAC address by querying the read-only field factory_mac_address in the Settings.Secure database. |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: scan: fix bus ID cleanup on device_add() failures
When device_add() fails after acpi_device_set_name() has allocated an
instance ID and a new acpi_device_bus_id has been linked into
acpi_bus_id_list, the rollback path only removes wakeup_list and
detaches the ACPI handle data.
That leaves the bus-ID bookkeeping behind and keeps the allocated
instance number consumed.
Move the bus-ID cleanup and wakeup-list removal into a single helper.
Use it from both the normal device teardown path and the device_add()
rollback path. The wakeup list node is initialized before registration,
so it can be deleted without checking whether the device is wakeup-
capable like in the original teardown path.

| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Clean up channels on setup failure
scmi_channels_setup() can fail after the common BASE channel or earlier
protocol channels have already been registered in the TX/RX IDRs.
Route this failure through the existing channel cleanup label so the
transport channels, transport devices and IDR state created before the
failure are released before the probe error path frees the SCMI instance
ID. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf,lsm: Drop bpf_prog_free from sleepable_lsm_hooks
__bpf_prog_put_rcu() is the call_rcu() callback for non-sleepable programs.
security_bpf_prog_free() called from there fires bpf_prog_free in softirq;
if a sleepable LSM prog is attached to that hook, might_fault() BUGs:
BUG: sleeping function called from invalid context
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 5038
preempt_count: 101, expected: 0
Call Trace:
<IRQ>

The call_rcu/call_rcu_tasks_trace split reflects the freed program's
sleepability, not that of any attached observer.
security_bpf_prog_free() also frees prog->aux->security, which has to stay
after the grace period, so drop bpf_prog_free from sleepable_lsm_hooks
rather than move the call. Non-sleepable observers still run there. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Release the export reference when reaping open stateids
nfs4_put_stid() releases the svc_export tracked in
nfs4_stid.sc_export, but free_ol_stateid_reaplist() frees open and
lock stateids by calling ->sc_free() directly, bypassing that path.
An open stateid takes an sc_export reference in nfs4_open() and a
lock stateid takes its own in init_lock_stateid(); both reach
free_ol_stateid_reaplist() through their normal teardown, the open
stateid via release_open_stateid() and the lock stateid via
nfsd4_release_lockowner(), each through put_ol_stateid_locked().
The reference is therefore never dropped, pinning the export and
blocking unmount for the lifetime of the stateid.
Release sc_export in free_ol_stateid_reaplist() the way
nfs4_put_stid() does. ->sc_free() runs once per stateid, and a
stateid reaches free_ol_stateid_reaplist() or nfs4_put_stid() but
never both, so the reference is dropped exactly once. Revoked
stateids reach this path with sc_export already cleared by
drop_stid_export(), so they are skipped rather than double-freed.
nfs4_put_stid() itself read sc_export before acquiring cl_lock.
drop_stid_export() clears that field and releases the reference
under cl_lock, so a concurrent revocation could drop the export in
the window between the read and the final put, releasing the same
reference twice. Read sc_export while cl_lock is held so the two
paths serialize and the reference is released exactly once. |
| The OpenFeature Operator allows users to expose feature flags to applications. In version 0.9.2 and earlier, a tenant who can create a controller-owned workload can use the openfeature.dev/featureflagsource annotation with NAMESPACE/NAME syntax to reference a FeatureFlagSource or InProcessConfiguration in another namespace. On multi-tenant clusters that use namespaces as trust boundaries, the cluster-scoped operator reads that resource and materializes spec.envVars literal values, spec.httpSyncBearerToken, sync URIs, and supporting ConfigMaps into the tenant's workload. Single-tenant clusters are not impacted, secretKeyRef and configMapKeyRef values remain namespace-local, and creating a FeatureFlagSource is not required. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio_balloon: quiesce balloon work before device shutdown
Commit 8bd2fa086a04 ("virtio: break and reset virtio devices on
device_shutdown()") added a generic virtio bus .shutdown handler that
breaks and resets every virtio device during device_shutdown(), i.e. on
reboot and kexec.
virtio_balloon provides no .shutdown of its own, so that generic path
runs while the balloon's asynchronous work is still armed. Once the
device has been broken, virtqueue_add_inbuf() in
virtballoon_free_page_report() returns -EIO and trips its
WARN_ON_ONCE(). On a kernel booted with panic_on_warn that turns an
ordinary reboot, for example a kexec based upgrade, into a fatal panic
in the middle of device_shutdown(), so the machine never reaches the
new kernel.
Relaxing that single WARN_ON_ONCE() would only hide the symptom: the
inflate/deflate and OOM paths do not warn, they call
wait_event(vb->acked, ...) and would instead block forever on a broken
queue that can no longer complete. The device has to be quiesced, not
just kept quiet.
Add a .shutdown handler that quiesces the balloon via the shared
virtballoon_quiesce() helper while the device is still alive, and only
then breaks and resets it via virtio_device_shutdown(). Unlike
virtballoon_remove() the balloon workqueue is not destroyed, as shutdown
does not free the device and cancel_work_sync() together with stop_update
already prevent any further work from being queued. |
| A vulnerability has been identified in the Acer System Monitoring component included with NitroSense and PredatorSense. A WebSocket service was configured to listen on all network interfaces, which may expose the service to unintended network access. |
| mport is the MidnightBSD Package Manager. Prior to 2.7.8, package installation lacked a preflight check for incoming non-directory assets that already existed on disk. The affected logic across libmport/check_preconditions.c, libmport/install_primative.c, and libmport/mport_private.h did not apply MPORT_PRECHECK_FILE_CONFLICTS, so a crafted or conflicting package could overwrite a file owned by another package or unmanaged by mport. The check is bypassed only when the operator explicitly enables mport->force. Privileged installation without that override could compromise local filesystem integrity and package database consistency. This issue is fixed in version 2.7.8. |
| MCP Documentation Server is a local-first document management and semantic search server for AI coding agents. From 1.13.0 until 1.13.1, the automatically started Web UI in src/server.ts calls startWebServer in src/web-server.ts with START_WEB_UI enabled by default and WEB_PORT set to 3080. startWebServer uses app.listen(PORT) without a host, which binds the unauthenticated document-management API to all interfaces rather than localhost. A network-reachable client can invoke GET /api/documents, GET /api/documents/:id, POST /api/documents, POST /api/search-all, DELETE /api/documents/:id, and GET /api/config without credentials to enumerate and read documents, search the corpus, insert or delete documents, and tamper with the MCP assistant's knowledge base. The service must be reachable from the attacker's LAN, VM network, container bridge, VPN, or another routed network, and the issue does not provide remote code execution. This issue is fixed in 1.13.1. |
| n8n's JavaScript task runner shared a single module cache across all users' Code-node executions. In affected versions (before 1.123.67, 2.31.5, and 2.32.1), a user able to run a Code node could poison a cached module and thereby alter other users' Code-node executions on the same runner, affecting their confidentiality, integrity, or availability. This is a cross-user isolation break within a single n8n instance and does not constitute a sandbox escape or remote code execution. Only multi-user instances running the JS task runner with built-in or external modules enabled are affected. |
| In the Linux kernel, the following vulnerability has been resolved:
media: chips-media: wave5: Defer job_finish() only when a DEC_PIC was queued
Decoder instances sharing a VPU also share one v4l2_m2m job slot, released
when the running context calls v4l2_m2m_job_finish(). While draining,
device_run() defers job_finish() once EOS is sent (sent_eos), expecting a
later finish_decode() (from a DEC_PIC completion IRQ) to release the slot.
But the m2m core checks job_ready() only when a job is queued, not when it
is dispatched. A job queued while draining can run after finish_decode()
has already moved the instance to STOP and sent EOS. device_run() then runs
in STOP, issues no DEC_PIC, yet still skips job_finish() - so no IRQ, no
finish_decode(), and the shared slot is leaked, stalling every instance.
With several v4l2h264dec instances in parallel, GStreamer hangs at EOS.
Track whether the run actually queued a DEC_PIC (cmd_issued) and defer
job_finish() only then. Otherwise finish the job immediately |
| vm2 versions 3.11.3 through 3.11.6 expose the host process's real https.globalAgent to sandboxed code when a NodeVM is explicitly configured to allow require('https'). The builtin loader wraps host modules in a read-only proxy, but method calls such as Agent.prototype.on() are forwarded to the underlying host object, so sandbox code can register a listener for the agent's 'free' event. When an unrelated host HTTPS request releases a pooled connection, the listener receives the live host request options and the host TLSSocket, allowing sandboxed code to read the host's Authorization header and private destination host/port, attach a data listener to the released socket and read subsequent host response bodies in plaintext, and issue attacker-chosen authenticated requests using the stolen credentials. The issue is fixed in 3.11.7. |
