In the Linux kernel, the following vulnerability has been resolved: hwmon: (ibmpex) Fix possible UAF when ibmpex_register_bmc() fails Smatch report warning as follows: drivers/hwmon/ibmpex.c:509 ibmpex_register_bmc() warn: '&data->list' not removed from list If ibmpex_find_sensors() fails in ibmpex_register_bmc(), data will be freed, but data->list will not be removed from driver_data.bmc_data, then list traversal may cause UAF. Fix by removeing it from driver_data.bmc_data before free(). • https://git.kernel.org/stable/c/57c7c3a0fdea95eddcaeba31e7ca7dfc917682ab https://git.kernel.org/stable/c/f2a13196ad41c6c2ab058279dffe6c97292e753a https://git.kernel.org/stable/c/798198273bf86673b970b51acdb35e57f42b3fcb https://git.kernel.org/stable/c/24b9633f7db7f4809be7053df1d2e117e7c2de10 https://git.kernel.org/stable/c/7b2b67fe1339389e0bf3c37c7a677a004ac0e4e3 https://git.kernel.org/stable/c/90907cd4d11351ff76c9a447bcb5db0e264c47cd https://git.kernel.org/stable/c/45f6e81863747c0d7bc6a95ec51129900e71467a https://git.kernel.org/stable/c/e65cfd1f9cd27d9c27ee5cb88128a9f79 •

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 •
