CVSS v3.1 |
| In OpenStack Ironic through 35.x, instance_info['ks_template'] is rendered without sandboxing. |
| In uriparser before 1.0.2, there is pointer difference truncation to int in various places. |
| In uriparser before 1.0.2, the function family EqualsUri can misclassify two unequal URIs as equal. |
| Weak credentials in the CashDro 3 web administration panel, version 24.01.00.26, where the platform allows the use of numeric PINs for user authentication. The system supports the use of PIN-based credentials, maintaining compatibility with POS software integrations deployed since 2012. This could allow an attacker to easily perform a brute-force attack against a user and gain access by trying different PINs without the account being locked. Successful exploitation of this vulnerability could result in unauthorized access to confidential configuration settings, compromising the security of the system. |
| OS command injection in Dashboard Server interface in Universal Robots PolyScope versions prior to 5.21.1 allows unauthenticated attacker to craft commands that will execute code on the robot's OS. |
| The E2Pdf – Export Pdf Tool for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' attribute of the `e2pdf-download` shortcode in all versions up to, and including, 1.32.17. This is due to insufficient input sanitization and output escaping on the shortcode attribute. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |
| A vulnerability in Remote Spark SparkView before build 1122 allows an attacker to bypasses the local connection check and achieve arbitrary code execution as root on the server side. Depending on implementation the vulnerability can be exploited by an unauthenticated attacker. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Add sanity check for OOB writes at silencing
At silencing the playback URB packets in the implicit fb mode before
the actual playback, we blindly assume that the received packets fit
with the buffer size. But when the setup in the capture stream
differs from the playback stream (e.g. due to the USB core limitation
of max packet size), such an inconsistency may lead to OOB writes to
the buffer, resulting in a crash.
For addressing it, add a sanity check of the transfer buffer size at
prepare_silent_urb(), and stop the data copy if the received data
overflows. Also, report back the transfer error properly from there,
too.
Note that this doesn't fix the root cause of the playback error
itself, but this merely covers the kernel Oops. |
| In the Linux kernel, the following vulnerability has been resolved:
media: chips-media: wave5: Fix Null reference while testing fluster
When multi instances are created/destroyed, many interrupts happens
and structures for decoder are removed.
"struct vpu_instance" this structure is shared for all flow in the decoder,
so if the structure is not protected by lock, Null dereference
could happens sometimes.
IRQ Handler was spilt to two phases and Lock was added as well. |
| In the Linux kernel, the following vulnerability has been resolved:
alpha: fix user-space corruption during memory compaction
Alpha systems can suffer sporadic user-space crashes and heap
corruption when memory compaction is enabled.
Symptoms include SIGSEGV, glibc allocator failures (e.g. "unaligned
tcache chunk"), and compiler internal errors. The failures disappear
when compaction is disabled or when using global TLB invalidation.
The root cause is insufficient TLB shootdown during page migration.
Alpha relies on ASN-based MM context rollover for instruction cache
coherency, but this alone is not sufficient to prevent stale data or
instruction translations from surviving migration.
Fix this by introducing a migration-specific helper that combines:
- MM context invalidation (ASN rollover),
- immediate per-CPU TLB invalidation (TBI),
- synchronous cross-CPU shootdown when required.
The helper is used only by migration/compaction paths to avoid changing
global TLB semantics.
Additionally, update flush_tlb_other(), pte_clear(), to use
READ_ONCE()/WRITE_ONCE() for correct SMP memory ordering.
This fixes observed crashes on both UP and SMP Alpha systems. |
| In the Linux kernel, the following vulnerability has been resolved:
media: qcom: camss: vfe: Fix out-of-bounds access in vfe_isr_reg_update()
vfe_isr() iterates using MSM_VFE_IMAGE_MASTERS_NUM(7) as the loop
bound and passes the index to vfe_isr_reg_update(). However,
vfe->line[] array is defined with VFE_LINE_NUM_MAX(4):
struct vfe_line line[VFE_LINE_NUM_MAX];
When index is 4, 5, 6, the access to vfe->line[line_id] exceeds
the array bounds and resulting in out-of-bounds memory access.
Fix this by using separate loops for output lines and write masters. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/amd: move wait_on_sem() out of spinlock
With iommu.strict=1, the existing completion wait path can cause soft
lockups under stressed environment, as wait_on_sem() busy-waits under the
spinlock with interrupts disabled.
Move the completion wait in iommu_completion_wait() out of the spinlock.
wait_on_sem() only polls the hardware-updated cmd_sem and does not require
iommu->lock, so holding the lock during the busy wait unnecessarily
increases contention and extends the time with interrupts disabled. |
| In the Linux kernel, the following vulnerability has been resolved:
9p/xen: protect xen_9pfs_front_free against concurrent calls
The xenwatch thread can race with other back-end change notifications
and call xen_9pfs_front_free() twice, hitting the observed general
protection fault due to a double-free. Guard the teardown path so only
one caller can release the front-end state at a time, preventing the
crash.
This is a fix for the following double-free:

| In the Linux kernel, the following vulnerability has been resolved:
vhost: move vdpa group bound check to vhost_vdpa
Remove duplication by consolidating these here. This reduces the
posibility of a parent driver missing them.
While we're at it, fix a bug in vdpa_sim where a valid ASID can be
assigned to a group equal to ngroups, causing an out of bound write. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: ->d_compare() must not block
... so don't use __getname() there. Switch it (and ntfs_d_hash(), while
we are at it) to kmalloc(PATH_MAX, GFP_NOWAIT). Yes, ntfs_d_hash()
almost certainly can do with smaller allocations, but let ntfs folks
deal with that - keep the allocation size as-is for now.
Stop abusing names_cachep in ntfs, period - various uses of that thing
in there have nothing to do with pathnames; just use k[mz]alloc() and
be done with that. For now let's keep sizes as-in, but AFAICS none of
the users actually want PATH_MAX. |

smb: client: prevent races in ->query_interfaces()

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Refactor amdgpu_gem_va_ioctl for Handling Last Fence Update and Timeline Management v4
This commit simplifies the amdgpu_gem_va_ioctl function, key updates
include:
- Moved the logic for managing the last update fence directly into
amdgpu_gem_va_update_vm.
- Introduced checks for the timeline point to enable conditional
replacement or addition of fences.
v2: Addressed review comments from Christian.
v3: Updated comments (Christian).
v4: The previous version selected the fence too early and did not manage its
reference correctly, which could lead to stale or freed fences being used.
This resulted in refcount underflows and could crash when updating GPU
timelines.
The fence is now chosen only after the VA mapping work is completed, and its
reference is taken safely. After exporting it to the VM timeline syncobj, the
driver always drops its local fence reference, ensuring balanced refcounting
and avoiding use-after-free on dma_fence.

[ 206.555667] Kernel panic - not syncing: Fatal exception in interrupt |
| In the Linux kernel, the following vulnerability has been resolved:
drm/atmel-hlcdc: fix use-after-free of drm_crtc_commit after release
The atmel_hlcdc_plane_atomic_duplicate_state() callback was copying
the atmel_hlcdc_plane state structure without properly duplicating the
drm_plane_state. In particular, state->commit remained set to the old
state commit, which can lead to a use-after-free in the next
drm_atomic_commit() call.
Fix this by calling
__drm_atomic_helper_duplicate_plane_state(), which correctly clones
the base drm_plane_state (including the ->commit pointer).
It has been seen when closing and re-opening the device node while
another DRM client (e.g. fbdev) is still attached:

| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack_h323: fix OOB read in decode_choice()
In decode_choice(), the boundary check before get_len() uses the
variable `len`, which is still 0 from its initialization at the top of
the function:
unsigned int type, ext, len = 0;
...
if (ext || (son->attr & OPEN)) {
BYTE_ALIGN(bs);
if (nf_h323_error_boundary(bs, len, 0)) /* len is 0 here */
return H323_ERROR_BOUND;
len = get_len(bs); /* OOB read */
When the bitstream is exactly consumed (bs->cur == bs->end), the check
nf_h323_error_boundary(bs, 0, 0) evaluates to (bs->cur + 0 > bs->end),
which is false. The subsequent get_len() call then dereferences
*bs->cur++, reading 1 byte past the end of the buffer. If that byte
has bit 7 set, get_len() reads a second byte as well.
This can be triggered remotely by sending a crafted Q.931 SETUP message
with a User-User Information Element containing exactly 2 bytes of
PER-encoded data ({0x08, 0x00}) to port 1720 through a firewall with
the nf_conntrack_h323 helper active. The decoder fully consumes the
PER buffer before reaching this code path, resulting in a 1-2 byte
heap-buffer-overflow read confirmed by AddressSanitizer.
Fix this by checking for 2 bytes (the maximum that get_len() may read)
instead of the uninitialized `len`. This matches the pattern used at
every other get_len() call site in the same file, where the caller
checks for 2 bytes of available data before calling get_len(). |

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
