https://notcve.org/view.php?id=CVE-2022-49029
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 •

https://notcve.org/view.php?id=CVE-2022-49026
In the Linux kernel, the following vulnerability has been resolved: e100: Fix possible use after free in e100_xmit_prepare In e100_xmit_prepare(), if we can't map the skb, then return -ENOMEM, so e100_xmit_frame() will return NETDEV_TX_BUSY and the upper layer will resend the skb. But the skb is already freed, which will cause UAF bug when the upper layer resends the skb. Remove the harmful free. • https://git.kernel.org/stable/c/5e5d49422dfb035ca9e280cd61d434095c151272 https://git.kernel.org/stable/c/b775f37d943966f6f77dca402f5a9dedce502c25 https://git.kernel.org/stable/c/9fc27d22cdb9b1fcd754599d216a8992fed280cd https://git.kernel.org/stable/c/b46f6144ab89d3d757ead940759c505091626a7d https://git.kernel.org/stable/c/45605c75c52c7ae7bfe902214343aabcfe5ba0ff •

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 •
