CVSS v3.1 |
| A stack-based buffer overflow in the tmpServer module of TP-Link Archer AX53 v1.0 allows an authenticated adjacent attacker to trigger a segmentation fault and potentially execute arbitrary code via a specially crafted configuration file. Successful exploitation may cause a crash and could allow arbitrary code execution, enabling modification of device state, exposure of sensitive data, or further compromise of device integrity.
This issue affects AX53 v1.0: before 1.7.1 Build 20260213. |
| In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Fix possible dereference of uninitialized pointer
There is a pointer head_page in rb_meta_validate_events() which is not
initialized at the beginning of a function. This pointer can be dereferenced
if there is a failure during reader page validation. In this case the control
is passed to "invalid" label where the pointer is dereferenced in a loop.
To fix the issue initialize orig_head and head_page before calling
rb_validate_buffer.
Found by Linux Verification Center (linuxtesting.org) with SVACE. |
| In the Linux kernel, the following vulnerability has been resolved:
net: mana: Fix double destroy_workqueue on service rescan PCI path
While testing corner cases in the driver, a use-after-free crash
was found on the service rescan PCI path.
When mana_serv_reset() calls mana_gd_suspend(), mana_gd_cleanup()
destroys gc->service_wq. If the subsequent mana_gd_resume() fails
with -ETIMEDOUT or -EPROTO, the code falls through to
mana_serv_rescan() which triggers pci_stop_and_remove_bus_device().
This invokes the PCI .remove callback (mana_gd_remove), which calls
mana_gd_cleanup() a second time, attempting to destroy the already-
freed workqueue. Fix this by NULL-checking gc->service_wq in
mana_gd_cleanup() and setting it to NULL after destruction.

| A hidden, persistent backdoor was found in Yarbo firmware v2.3.9 that provides remote, unauthenticated (or weakly authenticated) access to privileged functionality. The backdoor is undocumented, cannot be disabled via user-facing settings, and survives factory reset and ordinary firmware updates. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: validate connector number in ucsi_notify_common()
The connector number extracted from CCI via UCSI_CCI_CONNECTOR() is a
7-bit field (0-127) that is used to index into the connector array in
ucsi_connector_change(). However, the array is only allocated for the
number of connectors reported by the device (typically 2-4 entries).
A malicious or malfunctioning device could report an out-of-range
connector number in the CCI, causing an out-of-bounds array access in
ucsi_connector_change().
Add a bounds check in ucsi_notify_common(), the central point where CCI
is parsed after arriving from hardware, so that bogus connector numbers
are rejected before they propagate further. |

This issue affects Royal Elementor Addons: from n/a before 1.7.1053. |
| In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: possible double-free of cctx->remote_heap
fastrpc_init_create_static_process() may free cctx->remote_heap on the
err_map path but does not clear the pointer. Later, fastrpc_rpmsg_remove()
frees cctx->remote_heap again if it is non-NULL, which can lead to a
double-free if the INIT_CREATE_STATIC ioctl hits the error path and the rpmsg
device is subsequently removed/unbound.
Clear cctx->remote_heap after freeing it in the error path to prevent the
later cleanup from freeing it again.
This issue was found by an in-house analysis workflow that extracts AST-based
information and runs static checks, with LLM assistance for triage, and was
confirmed by manual code review.
No hardware testing was performed. |
| The Forminator Forms plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 1.51.1. This is due to the `processRequest()` method in `Forminator_Admin_Module_Edit_Page` (admin/abstracts/class-admin-module-edit-page.php) dispatching sensitive module-management actions — including export, delete, clone, delete-entries, publish/draft, and bulk variants — after only a nonce check, without ever verifying that the current user holds the `manage_forminator_modules` capability. The nonce used (`forminator_form_request`) is unconditionally embedded in the global `forminatorData` JavaScript object and localized on every Forminator admin page, including Templates and Reports pages accessible to users who explicitly lack module-management permissions. Because `processRequest()` is invoked during the `admin_menu` action hook — which fires before WordPress enforces page-level capability checks — a user whose Forminator role is restricted to Templates or Reports can craft a valid POST request targeting any published module and successfully trigger the vulnerable actions. This makes it possible for authenticated attackers with subscriber-level access (or any custom low-privilege Forminator role) to export the complete internal configuration of arbitrary forms/polls/quizzes (including notification routing, integration credentials, and conditional logic), delete modules, delete all submissions/votes, clone modules, or bulk-change publish/draft status. |
| Jenkins Credentials Binding Plugin 719.v80e905ef14eb_ and earlier does not sanitize file names for file and zip file credentials, allowing attackers able to provide credentials to a job to write files to arbitrary locations on the node filesystem, which can lead to remote code execution if Jenkins is configured to allow a low-privileged user to configure file or zip file credentials used for a job running on the built-in node. |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: of: display_timing: fix refcount leak in of_get_display_timings()
of_parse_phandle() returns a device_node with refcount incremented,
which is stored in 'entry' and then copied to 'native_mode'. When the
error paths at lines 184 or 192 jump to 'entryfail', native_mode's
refcount is not decremented, causing a refcount leak.
Fix this by changing the goto target from 'entryfail' to 'timingfail',
which properly calls of_node_put(native_mode) before cleanup. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Ignore -EBUSY when checking nested events from vcpu_block()
Ignore -EBUSY when checking nested events after exiting a blocking state
while L2 is active, as exiting to userspace will generate a spurious
userspace exit, usually with KVM_EXIT_UNKNOWN, and likely lead to the VM's
demise. Continuing with the wakeup isn't perfect either, as *something*
has gone sideways if a vCPU is awakened in L2 with an injected event (or
worse, a nested run pending), but continuing on gives the VM a decent
chance of surviving without any major side effects.
As explained in the Fixes commits, it _should_ be impossible for a vCPU to
be put into a blocking state with an already-injected event (exception,
IRQ, or NMI). Unfortunately, userspace can stuff MP_STATE and/or injected
events, and thus put the vCPU into what should be an impossible state.
Don't bother trying to preserve the WARN, e.g. with an anti-syzkaller
Kconfig, as WARNs can (hopefully) be added in paths where _KVM_ would be
violating x86 architecture, e.g. by WARNing if KVM attempts to inject an
exception or interrupt while the vCPU isn't running. |
| In the Linux kernel, the following vulnerability has been resolved:
hfsplus: pretend special inodes as regular files
Since commit af153bb63a33 ("vfs: catch invalid modes in may_open()")
requires any inode be one of S_IFDIR/S_IFLNK/S_IFREG/S_IFCHR/S_IFBLK/
S_IFIFO/S_IFSOCK type, use S_IFREG for special inodes. |

| In the Linux kernel, the following vulnerability has been resolved:
md-cluster: fix NULL pointer dereference in process_metadata_update
The function process_metadata_update() blindly dereferences the 'thread'
pointer (acquired via rcu_dereference_protected) within the wait_event()
macro.
While the code comment states "daemon thread must exist", there is a valid
race condition window during the MD array startup sequence (md_run):
1. bitmap_load() is called, which invokes md_cluster_ops->join().
2. join() starts the "cluster_recv" thread (recv_daemon).
3. At this point, recv_daemon is active and processing messages.
4. However, mddev->thread (the main MD thread) is not initialized until
later in md_run().
If a METADATA_UPDATED message is received from a remote node during this
specific window, process_metadata_update() will be called while
mddev->thread is still NULL, leading to a kernel panic.
To fix this, we must validate the 'thread' pointer. If it is NULL, we
release the held lock (no_new_dev_lockres) and return early, safely
ignoring the update request as the array is not yet fully ready to
process it. |
| In the Linux kernel, the following vulnerability has been resolved:
APEI/GHES: ensure that won't go past CPER allocated record
The logic at ghes_new() prevents allocating too large records, by
checking if they're bigger than GHES_ESTATUS_MAX_SIZE (currently, 64KB).
Yet, the allocation is done with the actual number of pages from the
CPER bios table location, which can be smaller.
Yet, a bad firmware could send data with a different size, which might
be bigger than the allocated memory, causing an OOPS:
