CVSS v3.1 |
| A flaw was found in Undertow that can cause remote denial of service attacks. When the server uses the FormEncodedDataDefinition.doParse(StreamSourceChannel) method to parse large form data encoding with application/x-www-form-urlencoded, the method will cause an OutOfMemory issue. This flaw allows unauthorized users to cause a remote denial of service (DoS) attack. |
| OpenClaw's Nextcloud Talk plugin versions prior to 2026.2.6 accept equality matching on the mutable actor.name display name field for allowlist validation, allowing attackers to bypass DM and room allowlists. An attacker can change their Nextcloud display name to match an allowlisted user ID and gain unauthorized access to restricted conversations. |
| Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.8, the GetSettings API handler (api/settings/settings.go:24-65) serializes all settings structs to JSON and returns them to authenticated users. Many sensitive fields are tagged with protected:"true" - however, this tag is only enforced during writes (via ProtectedFill in SaveSettings) and is completely ignored during reads. This exposes 40+ protected fields including JwtSecret (enabling auth token forgery), NodeSecret (enabling cluster node impersonation), OIDC ClientSecret (enabling OAuth account takeover), and the IP whitelist configuration. This issue has been patched in version 2.3.8. |
| Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.8, nginx-ui exposes a backup restore endpoint (POST /api/restore) that is completely unauthenticated during the first 10 minutes after process startup on any fresh installation. An unauthenticated remote attacker can upload a crafted backup archive that overwrites the application's configuration file (app.ini) and SQLite database. Because the attacker controls the restored app.ini, they can inject an arbitrary OS command into the TestConfigCmd setting. After the application automatically restarts to apply the restored config, a single follow-up request triggers that command as the user running nginx-ui — typically root in Docker deployments. This issue has been patched in version 2.3.8. |
| In the Linux kernel, the following vulnerability has been resolved:
LoongArch: Make cpumask_of_node() robust against NUMA_NO_NODE
The arch definition of cpumask_of_node() cannot handle NUMA_NO_NODE -
which is a valid index - so add a check for this. |
| In the Linux kernel, the following vulnerability has been resolved:
net: cpsw_new: Fix potential unregister of netdev that has not been registered yet
If an error occurs during register_netdev() for the first MAC in
cpsw_register_ports(), even though cpsw->slaves[0].ndev is set to NULL,
cpsw->slaves[1].ndev would remain unchanged. This could later cause
cpsw_unregister_ports() to attempt unregistering the second MAC.
To address this, add a check for ndev->reg_state before calling
unregister_netdev(). With this change, setting cpsw->slaves[i].ndev
to NULL becomes unnecessary and can be removed accordingly. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring/zcrx: fix sgtable leak on mapping failures
In an unlikely case when io_populate_area_dma() fails, which could only
happen on a PAGE_POOL_32BIT_ARCH_WITH_64BIT_DMA machine,
io_zcrx_map_area() will have an initialised and not freed table. It was
supposed to be cleaned up in the error path, but !is_mapped prevents
that. |
| In the Linux kernel, the following vulnerability has been resolved:
net/rds: No shortcut out of RDS_CONN_ERROR
RDS connections carry a state "rds_conn_path::cp_state"
and transitions from one state to another and are conditional
upon an expected state: "rds_conn_path_transition."
There is one exception to this conditionality, which is
"RDS_CONN_ERROR" that can be enforced by "rds_conn_path_drop"
regardless of what state the condition is currently in.
But as soon as a connection enters state "RDS_CONN_ERROR",
the connection handling code expects it to go through the
shutdown-path.
The RDS/TCP multipath changes added a shortcut out of
"RDS_CONN_ERROR" straight back to "RDS_CONN_CONNECTING"
via "rds_tcp_accept_one_path" (e.g. after "rds_tcp_state_change").
A subsequent "rds_tcp_reset_callbacks" can then transition
the state to "RDS_CONN_RESETTING" with a shutdown-worker queued.
That'll trip up "rds_conn_init_shutdown", which was
never adjusted to handle "RDS_CONN_RESETTING" and subsequently
drops the connection with the dreaded "DR_INV_CONN_STATE",
which leaves "RDS_SHUTDOWN_WORK_QUEUED" on forever.
So we do two things here:
a) Don't shortcut "RDS_CONN_ERROR", but take the longer
path through the shutdown code.
b) Add "RDS_CONN_RESETTING" to the expected states in
"rds_conn_init_shutdown" so that we won't error out
and get stuck, if we ever hit weird state transitions
like this again." |
| In the Linux kernel, the following vulnerability has been resolved:
clocksource/drivers/sh_tmu: Always leave device running after probe
The TMU device can be used as both a clocksource and a clockevent
provider. The driver tries to be smart and power itself on and off, as
well as enabling and disabling its clock when it's not in operation.
This behavior is slightly altered if the TMU is used as an early
platform device in which case the device is left powered on after probe,
but the clock is still enabled and disabled at runtime.
This has worked for a long time, but recent improvements in PREEMPT_RT
and PROVE_LOCKING have highlighted an issue. As the TMU registers itself
as a clockevent provider, clockevents_register_device(), it needs to use
raw spinlocks internally as this is the context of which the clockevent
framework interacts with the TMU driver. However in the context of
holding a raw spinlock the TMU driver can't really manage its power
state or clock with calls to pm_runtime_*() and clk_*() as these calls
end up in other platform drivers using regular spinlocks to control
power and clocks.
This mix of spinlock contexts trips a lockdep warning.

| In the Linux kernel, the following vulnerability has been resolved:
media: chips-media: wave5: Fix device cleanup order to prevent kernel panic
Move video device unregistration to the beginning of the remove function
to ensure all video operations are stopped before cleaning up the worker
thread and disabling PM runtime. This prevents hardware register access
after the device has been powered down.
In polling mode, the hrtimer periodically triggers
wave5_vpu_timer_callback() which queues work to the kthread worker.
The worker executes wave5_vpu_irq_work_fn() which reads hardware
registers via wave5_vdi_read_register().
The original cleanup order disabled PM runtime and powered down hardware
before unregistering video devices. When autosuspend triggers and powers
off the hardware, the video devices are still registered and the worker
thread can still be triggered by the hrtimer, causing it to attempt
reading registers from powered-off hardware. This results in a bus error
(synchronous external abort) and kernel panic.
This causes random kernel panics during encoding operations:

net: wan: farsync: Fix use-after-free bugs caused by unfinished tasklets
When the FarSync T-series card is being detached, the fst_card_info is

| In the Linux kernel, the following vulnerability has been resolved:
media: iris: Add missing platform data entries for SM8750
Two platform-data fields for SM8750 were missed:
- get_vpu_buffer_size = iris_vpu33_buf_size
Without this, the driver fails to allocate the required internal
buffers, leading to basic decode/encode failures during session
bring-up.
- max_core_mbps = ((7680 * 4320) / 256) * 60
Without this capability exposed, capability checks are incomplete and
v4l2-compliance for encoder fails. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_skbedit: fix divide-by-zero in tcf_skbedit_hash()
Commit 38a6f0865796 ("net: sched: support hash selecting tx queue")
added SKBEDIT_F_TXQ_SKBHASH support. The inclusive range size is
computed as:
mapping_mod = queue_mapping_max - queue_mapping + 1;
The range size can be 65536 when the requested range covers all possible
u16 queue IDs (e.g. queue_mapping=0 and queue_mapping_max=U16_MAX).
That value cannot be represented in a u16 and previously wrapped to 0,
so tcf_skbedit_hash() could trigger a divide-by-zero:
queue_mapping += skb_get_hash(skb) % params->mapping_mod;
Compute mapping_mod in a wider type and reject ranges larger than U16_MAX
to prevent params->mapping_mod from becoming 0 and avoid the crash. |

Trying to access link enc on a dpia link will cause a crash otherwise |
| WebSocket endpoints lack proper authentication mechanisms, enabling attackers to perform unauthorized station impersonation and manipulate data sent to the backend. An unauthenticated attacker can connect to the OCPP WebSocket endpoint using a known or discovered charging station identifier, then issue or receive OCPP commands as a legitimate charger. Given that no authentication is required, this can lead to privilege escalation, unauthorized control of charging infrastructure, and corruption of charging network data reported to the backend. |
| The WebSocket backend uses charging station identifiers to uniquely associate sessions but allows multiple endpoints to connect using the same session identifier. This implementation results in predictable session identifiers and enables session hijacking or shadowing, where the most recent connection displaces the legitimate charging station and receives backend commands intended for that station. This vulnerability may allow unauthorized users to authenticate as other users or enable
a malicious actor to cause a denial-of-service condition by overwhelming the backend with valid session requests. |
