| In the Linux kernel, the following vulnerability has been resolved:
Input: edt-ft5x06 - fix use-after-free in debugfs teardown
The commit 68743c500c6e ("Input: edt-ft5x06 - use per-client debugfs
directory") removed the manual debugfs teardown, relying on the I2C core
to handle it. However, this creates a window where debugfs files are
still accessible after edt_ft5x06_ts_teardown_debugfs() frees
tsdata->raw_buffer.
To prevent a use-after-free, protect the freeing of raw_buffer with the
device mutex and set raw_buffer to NULL. The debugfs read function
already checks if raw_buffer is NULL under the same mutex, so this
safely avoids the use-after-free. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: reject zero shift in nft_bitwise
Reject zero shift operands for nft_bitwise left and right shift
expressions during initialization.
The carry propagation logic computes the carry from the adjacent 32-bit
word using BITS_PER_TYPE(u32) - shift. A zero shift operand turns this
into a 32-bit shift, which is undefined behaviour.
Reject zero shift operands in the control plane, alongside the existing
check for values greater than or equal to 32, so malformed rules never
reach the packet path. |
| In the Linux kernel, the following vulnerability has been resolved:
can: ucan: fix devres lifetime
USB drivers bind to USB interfaces and any device managed resources
should have their lifetime tied to the interface rather than parent USB
device. This avoids issues like memory leaks when drivers are unbound
without their devices being physically disconnected (e.g. on probe
deferral or configuration changes).
Fix the control message buffer lifetime so that it is released on driver
unbind. |
| IBM WebSphere Application Server - Liberty 22.0.0.11 through 26.0.0.5 IBM WebSphere Application Server Liberty could allow a remote attacker to bypass security under limited conditions by exploiting a specific timing window. |
| Hitachi Vantara Pentaho Data Integration & Analytics versions before 10.2.0.6 and 11.0.0.0, including 9.3.x and 8.3.x, does not apply ACLs on certain API endpoints related to platform mail notfications. |
| Attackers carefully craft malicious scripts, such as JavaScript, and inject them into target systems; when other users access pages containing such malicious content, the scripts are automatically loaded and executed in the victim's browser.Attackers can thereby steal user cookies, hijack session privileges, and tamper with page content.Since the malicious code is stored within the system, the attack scope is broad and the concealment is strong, making it frequently employed for data theft attacks. |
| Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.2.1, render_toc_ul() builds a <ul> table-of-contents tree from a list of (level, id, text) tuples. Both the id value (used as href="#<id>") and the text value (used as the visible link label) are inserted into <a> tags via a plain Python format string — with no HTML escaping applied to either value. When heading IDs are derived from user-supplied heading text (the standard use-case for readable slug anchors), an attacker can craft a heading whose text breaks out of the href="#..." attribute context, injecting arbitrary HTML tags including <script> blocks directly into the rendered TOC. This vulnerability is fixed in 3.2.1. |
| GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.2 before 18.10.7, 18.11 before 18.11.4, and 19.0 before 19.0.1 that under certain conditions could have allowed an unauthorized user to enumerate private projects due to incorrect authorization checks. |
| In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: auth_gss: fix memory leaks in XDR decoding error paths
The gssx_dec_ctx(), gssx_dec_status(), and gssx_dec_name()
functions allocate memory via gssx_dec_buffer(), which calls
kmemdup(). When a subsequent decode operation fails, these
functions return immediately without freeing previously
allocated buffers, causing memory leaks.
The leak in gssx_dec_ctx() is particularly relevant because
the caller (gssp_accept_sec_context_upcall) initializes several
buffer length fields to non-zero values, resulting in memory
allocation:
struct gssx_ctx rctxh = {
.exported_context_token.len = GSSX_max_output_handle_sz,
.mech.len = GSS_OID_MAX_LEN,
.src_name.display_name.len = GSSX_max_princ_sz,
.targ_name.display_name.len = GSSX_max_princ_sz
};
If, for example, gssx_dec_name() succeeds for src_name but
fails for targ_name, the memory allocated for
exported_context_token, mech, and src_name.display_name
remains unreferenced and cannot be reclaimed.
Add error handling with goto-based cleanup to free any
previously allocated buffers before returning an error. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: smartpqi: Fix memory leak in pqi_report_phys_luns()
pqi_report_phys_luns() fails to release the rpl_list buffer when
encountering an unsupported data format or when the allocation for
rpl_16byte_wwid_list fails. These early returns bypass the cleanup logic,
leading to memory leaks.
Consolidate the error handling by adding an out_free_rpl_list label and use
goto statements to ensure rpl_list is consistently freed on failure.
Compile tested only. Issue found using a prototype static analysis tool and
code review. |
| In the Linux kernel, the following vulnerability has been resolved:
mfd: arizona: Fix regulator resource leak on wm5102_clear_write_sequencer() failure
The wm5102_clear_write_sequencer() helper may return an error
and just return, bypassing the cleanup sequence and causing
regulators to remain enabled, leading to a resource leak.
Change the direct return to jump to the err_reset label to
properly free the resources. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: intel-ish-hid: fix NULL-ptr-deref in ishtp_bus_remove_all_clients
During a warm reset flow, the cl->device pointer may be NULL if the
reset occurs while clients are still being enumerated. Accessing
cl->device->reference_count without a NULL check leads to a kernel panic.
This issue was identified during multi-unit warm reboot stress clycles.
Add a defensive NULL check for cl->device to ensure stability under
such intensive testing conditions.

| In the Linux kernel, the following vulnerability has been resolved:
soc: mediatek: svs: Fix memory leak in svs_enable_debug_write()
In svs_enable_debug_write(), the buf allocated by memdup_user_nul()
is leaked if kstrtoint() fails.
Fix this by using __free(kfree) to automatically free buf, eliminating
the need for explicit kfree() calls and preventing leaks.

| In the Linux kernel, the following vulnerability has been resolved:
clk: mediatek: Drop __initconst from gates
Since commit 8ceff24a754a ("clk: mediatek: clk-gate: Refactor
mtk_clk_register_gate to use mtk_gate struct") the mtk_gate structs
are no longer just used for initialization/registration, but also at
runtime. So drop __initconst annotations. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: fix role switching during resume
If the role change while we are suspended, the cdns3 driver switches to the
new mode during resume. However, switching to host mode in this context
causes a NULL pointer dereference.
The host role's start() operation registers a xhci-hcd device, but its
probe is deferred while we are in the resume path. The host role's resume()
operation assumes the xhci-hcd device is already probed, which is not the
case, leading to the dereference. Since the start() operation of the new
role is already called, the resume operation can be skipped.
So skip the resume operation for the new role if a role switch occurs
during resume. Once the resume sequence is complete, the xhci-hcd device
can be probed in case of host mode.

| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix dirtyclusters double decrement on fs shutdown
fstests test generic/388 occasionally reproduces a warning in
ext4_put_super() associated with the dirty clusters count:
WARNING: CPU: 7 PID: 76064 at fs/ext4/super.c:1324 ext4_put_super+0x48c/0x590 [ext4]
Tracing the failure shows that the warning fires due to an
s_dirtyclusters_counter value of -1. IOW, this appears to be a
spurious decrement as opposed to some sort of leak. Further tracing
of the dirty cluster count deltas and an LLM scan of the resulting
output identified the cause as a double decrement in the error path
between ext4_mb_mark_diskspace_used() and the caller
ext4_mb_new_blocks().
First, note that generic/388 is a shutdown vs. fsstress test and so
produces a random set of operations and shutdown injections. In the
problematic case, the shutdown triggers an error return from the
ext4_handle_dirty_metadata() call(s) made from
ext4_mb_mark_context(). The changed value is non-zero at this point,
so ext4_mb_mark_diskspace_used() does not exit after the error
bubbles up from ext4_mb_mark_context(). Instead, the former
decrements both cluster counters and returns the error up to
ext4_mb_new_blocks(). The latter falls into the !ar->len out path
which decrements the dirty clusters counter a second time, creating
the inconsistency.
To avoid this problem and simplify ownership of the cluster
reservation in this codepath, lift the counter reduction to a single
place in the caller. This makes it more clear that
ext4_mb_new_blocks() is responsible for acquiring cluster
reservation (via ext4_claim_free_clusters()) in the !delalloc case
as well as releasing it, regardless of whether it ends up consumed
or returned due to failure. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix memory leak in GET_DATA_DIRECT_SYSFS_PATH handler
The UVERBS_HANDLER(MLX5_IB_METHOD_GET_DATA_DIRECT_SYSFS_PATH) function
allocates memory for the device path using kobject_get_path(). If the
length of the device path exceeds the output buffer length, the function
returns -ENOSPC but does not free the allocated memory, resulting in a
memory leak.
Add a kfree() call to the error path to ensure the allocated memory is
properly freed.
Compile tested only. Issue found using a prototype static analysis tool
and code review. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: call ksmbd_vfs_kern_path_end_removing() on some error paths
There are two places where ksmbd_vfs_kern_path_end_removing() needs to be
called in order to balance what the corresponding successful call to
ksmbd_vfs_kern_path_start_removing() has done, i.e. drop inode locks and
put the taken references. Otherwise there might be potential deadlocks
and unbalanced locks which are caught like:

| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix tcx/netkit detach permissions when prog fd isn't given
This commit fixes a security issue where BPF_PROG_DETACH on tcx or
netkit devices could be executed by any user when no program fd was
provided, bypassing permission checks. The fix adds a capability
check for CAP_NET_ADMIN or CAP_SYS_ADMIN in this case. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Preserve id of register in sync_linked_regs()
sync_linked_regs() copies the id of known_reg to reg when propagating
bounds of known_reg to reg using the off of known_reg, but when
known_reg was linked to reg like:
known_reg = reg ; both known_reg and reg get same id
known_reg += 4 ; known_reg gets off = 4, and its id gets BPF_ADD_CONST
now when a call to sync_linked_regs() happens, let's say with the following:
if known_reg >= 10 goto pc+2
known_reg's new bounds are propagated to reg but now reg gets
BPF_ADD_CONST from the copy.
This means if another link to reg is created like:
another_reg = reg ; another_reg should get the id of reg but
assign_scalar_id_before_mov() sees
BPF_ADD_CONST on reg and assigns a new id to it.
As reg has a new id now, known_reg's link to reg is broken. If we find
new bounds for known_reg, they will not be propagated to reg.
This can be seen in the selftest added in the next commit:
0: (85) call bpf_get_prandom_u32#7 ; R0=scalar()
1: (57) r0 &= 255 ; R0=scalar(smin=smin32=0,smax=umax=smax32=umax32=255,var_off=(0x0; 0xff))
2: (bf) r1 = r0 ; R0=scalar(id=1,smin=smin32=0,smax=umax=smax32=umax32=255,var_off=(0x0; 0xff)) R1=scalar(id=1,smin=smin32=0,smax=umax=smax32=umax32=255,var_off=(0x0; 0xff))
3: (07) r1 += 4 ; R1=scalar(id=1+4,smin=umin=smin32=umin32=4,smax=umax=smax32=umax32=259,var_off=(0x0; 0x1ff))
4: (a5) if r1 < 0xa goto pc+4 ; R1=scalar(id=1+4,smin=umin=smin32=umin32=10,smax=umax=smax32=umax32=259,var_off=(0x0; 0x1ff))
5: (bf) r2 = r0 ; R0=scalar(id=2,smin=umin=smin32=umin32=6,smax=umax=smax32=umax32=255) R2=scalar(id=2,smin=umin=smin32=umin32=6,smax=umax=smax32=umax32=255)
6: (a5) if r1 < 0xe goto pc+2 ; R1=scalar(id=1+4,smin=umin=smin32=umin32=14,smax=umax=smax32=umax32=259,var_off=(0x0; 0x1ff))
7: (35) if r0 >= 0xa goto pc+1 ; R0=scalar(id=2,smin=umin=smin32=umin32=6,smax=umax=smax32=umax32=9,var_off=(0x0; 0xf))
8: (37) r0 /= 0
div by zero
When 4 is verified, r1's bounds are propagated to r0 but r0 also gets
BPF_ADD_CONST (bug).
When 5 is verified, r0 gets a new id (2) and its link with r1 is broken.
After 6 we know r1 has bounds [14, 259] and therefore r0 should have
bounds [10, 255], therefore the branch at 7 is always taken. But because
r0's id was changed to 2, r1's new bounds are not propagated to r0.
The verifier still thinks r0 has bounds [6, 255] before 7 and execution
can reach div by zero.
Fix this by preserving id in sync_linked_regs() like off and subreg_def. |
