CVSS v3.1 |
| wheel is a command line tool for manipulating Python wheel files, as defined in PEP 427. In versions 0.40.0 through 0.46.1, the unpack function is vulnerable to file permission modification through mishandling of file permissions after extraction. The logic blindly trusts the filename from the archive header for the chmod operation, even though the extraction process itself might have sanitized the path. Attackers can craft a malicious wheel file that, when unpacked, changes the permissions of critical system files (e.g., /etc/passwd, SSH keys, config files), allowing for Privilege Escalation or arbitrary code execution by modifying now-writable scripts. This issue has been fixed in version 0.46.2. |
| In FIPS mode, Libreswan's add_decoded_cert() function calls CERT_ExtractPublicKey() and asserts that the result is not NULL. However, CERT_ExtractPublicKey() returns NULL when public key extraction fails, for example if the RSA exponent is set to 0. A remote attacker can send a malformed X.509 certificate in a CERT payload to trigger the assertion, causing the pluto daemon to abort and restart. Continued exploitation causes a denial of service. No remote code execution is possible. Both IKEv1 and IKEv2 are affected. The vulnerability is only exploitable when both the OS and libreswan are running in FIPS mode and at least one CA certificate is loaded. The CERT payload is processed before peer authentication, so no credentials are needed to exploit this. Configurations using only PreSharedKey (PSK) authentication with no CA certificates loaded in the NSS database are not vulnerable. |
| GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.2 before 18.11.11, 19.0 before 19.0.8, 19.1 before 19.1.6, and 19.2 before 19.2.4 that under certain conditions could have allowed an unauthenticated user to execute mutations via GET requests due to improper request validation in GraphQL multiplex query handling. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix use-after-free in offloaded map/prog info fill
When querying info for an offloaded BPF map or program,
bpf_map_offload_info_fill_ns() and bpf_prog_offload_info_fill_ns()
obtain the network namespace with get_net(dev_net(offmap->netdev)).
However, the associated netdev's netns may be racing with teardown
during netns destruction. If the netns refcount has already reached 0,
get_net() performs a refcount_t increment on 0, triggering:
refcount_t: addition on 0; use-after-free.
Although rtnl_lock and bpf_devs_lock ensure the netdev pointer remains
valid, they cannot prevent the netns refcount from reaching zero.
Fix this by using maybe_get_net() instead of get_net(). maybe_get_net()
uses refcount_inc_not_zero() and returns NULL if the refcount is already
zero, which causes ns_get_path_cb() to fail and the caller to return
-ENOENT -- the correct behavior when the netns is being destroyed. |
| In the Linux kernel, the following vulnerability has been resolved:
smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match().
smc_clc_prfx_match() is called from smc_listen_work() and
not under RCU nor RTNL.
Using sk_dst_get(sk)->dev could trigger UAF.
Let's use __sk_dst_get() and dst_dev_rcu().
Note that the returned value of smc_clc_prfx_match() is not
used in the caller. |
| In the Linux kernel, the following vulnerability has been resolved:
smc: Fix use-after-free in __pnet_find_base_ndev().
syzbot reported use-after-free of net_device in __pnet_find_base_ndev(),
which was called during connect(). [0]
smc_pnet_find_ism_resource() fetches sk_dst_get(sk)->dev and passes
down to pnet_find_base_ndev(), where RTNL is held. Then, UAF happened
at __pnet_find_base_ndev() when the dev is first used.
This means dev had already been freed before acquiring RTNL in
pnet_find_base_ndev().
While dev is going away, dst->dev could be swapped with blackhole_netdev,
and the dev's refcnt by dst will be released.
We must hold dev's refcnt before calling smc_pnet_find_ism_resource().
Also, smc_pnet_find_roce_resource() has the same problem.
Let's use __sk_dst_get() and dst_dev_rcu() in the two functions.

| In the Linux kernel, the following vulnerability has been resolved:
ibmvnic: Use kernel helpers for hex dumps
Previously, when the driver was printing hex dumps, the buffer was cast
to an 8 byte long and printed using string formatters. If the buffer
size was not a multiple of 8 then a read buffer overflow was possible.
Therefore, create a new ibmvnic function that loops over a buffer and
calls hex_dump_to_buffer instead.
This patch address KASAN reports like the one below:

| In the Linux kernel, the following vulnerability has been resolved:
jfs: add check read-only before truncation in jfs_truncate_nolock()
Added a check for "read-only" mode in the `jfs_truncate_nolock`
function to avoid errors related to writing to a read-only
filesystem.
Call stack:
block_write_begin() {
jfs_write_failed() {
jfs_truncate() {
jfs_truncate_nolock() {
txEnd() {
...
log = JFS_SBI(tblk->sb)->log;
// (log == NULL)
If the `isReadOnly(ip)` condition is triggered in
`jfs_truncate_nolock`, the function execution will stop, and no
further data modification will occur. Instead, the `xtTruncate`
function will be called with the "COMMIT_WMAP" flag, preventing
modifications in "read-only" mode. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Remove tst_run from lwt_seg6local_prog_ops.
The syzbot reported that the lwt_seg6 related BPF ops can be invoked
via bpf_test_run() without without entering input_action_end_bpf()
first.
Martin KaFai Lau said that self test for BPF_PROG_TYPE_LWT_SEG6LOCAL
probably didn't work since it was introduced in commit 04d4b274e2a
("ipv6: sr: Add seg6local action End.BPF"). The reason is that the
per-CPU variable seg6_bpf_srh_states::srh is never assigned in the self
test case but each BPF function expects it.
Remove test_run for BPF_PROG_TYPE_LWT_SEG6LOCAL. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: starfive - Do not free stack buffer
RSA text data uses variable length buffer allocated in software stack.
Calling kfree on it causes undefined behaviour in subsequent operations. |

wifi: ath11k: Add missing hw_ops->get_ring_selector() for IPQ5018
During sending data after clients connected, hw_ops->get_ring_selector()
will be called. But for IPQ5018, this member isn't set, and the
