In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix use-after-free when reverting termination table When having multiple dests with termination tables and second one or afterwards fails the driver reverts usage of term tables but doesn't reset the assignment in attr->dests[num_vport_dests].termtbl which case a use-after-free when releasing the rule. Fix by resetting the assignment of termtbl to null. • https://git.kernel.org/stable/c/10caabdaad5ace85577a453da97d1f8d3b944427 https://git.kernel.org/stable/c/0a2d73a77060c3cbdc6e801cd5d979d674cd404b https://git.kernel.org/stable/c/0d2f9d95d9fbe993f3c4bafb87d59897b0325aff https://git.kernel.org/stable/c/372eb550faa0757349040fd43f59483cbfdb2c0b https://git.kernel.org/stable/c/e6d2d26a49c3a9cd46b232975e45236304810904 https://git.kernel.org/stable/c/52c795af04441d76f565c4634f893e5b553df2ae •

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: fix buffer overflow in elem comparison For vendor elements, the code here assumes that 5 octets are present without checking.

https://notcve.org/view.php?id=CVE-2022-49020
In the Linux kernel, the following vulnerability has been resolved: net/9p: Fix a potential socket leak in p9_socket_open Both p9_fd_create_tcp() and p9_fd_create_unix() will call p9_socket_open(). If the creation of p9_trans_fd fails, p9_fd_create_tcp() and p9_fd_create_unix() will return an error directly instead of releasing the cscoket, which will result in a socket leak. This patch adds sock_release() to fix the leak issue. • https://git.kernel.org/stable/c/6b18662e239a032f908b7f6e164bdf7e2e0a32c9 https://git.kernel.org/stable/c/0396227f4daf4792a6a8aaa3b7771dc25c4cd443 https://git.kernel.org/stable/c/ded893965b895b2dccd3d1436d8d3daffa23ea64 https://git.kernel.org/stable/c/8b14bd0b500aec1458b51cb621c8e5fab3304260 https://git.kernel.org/stable/c/2d24d91b9f44620824fc37b766f7cae00ca32748 https://git.kernel.org/stable/c/e01c1542379fb395e7da53706df598f38905dfbf https://git.kernel.org/stable/c/8782b32ef867de7981bbe9e86ecb90e92e8780bd https://git.kernel.org/stable/c/aa08323fe18cb7cf95317ffa2d54ca1de •
