In the Linux kernel, the following vulnerability has been resolved: media: pci: cx23885: check cx23885_vdev_init() return cx23885_vdev_init() can return a NULL pointer, but that pointer is used in the next line without a check. Add a NULL pointer check and go to the error unwind if it is NULL. • https://git.kernel.org/stable/c/8e31b096e2e1949bc8f0be019c9ae70d414404c6 https://git.kernel.org/stable/c/199a42fc4c45e8b7f19efeb15dbc36889a599ac2 https://git.kernel.org/stable/c/e7385510e2550a9f8b6f3d5f33c5b894ab9ba976 https://git.kernel.org/stable/c/a5f1d30c51c485cec7a7de60205667c3ff86c303 https://git.kernel.org/stable/c/06ee04a907d64ee3910fecedd05d7f1be4b1b70e https://git.kernel.org/stable/c/b1397fb4a779fca560c43d2acf6702d41b4a495b https://git.kernel.org/stable/c/15126b916e39b0cb67026b0af3c014bfeb1f76b3 •

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 •
