  - In the Linux kernel, the following vulnerability has been resolved: rethook: fix a potential memleak in     rethook_alloc() In rethook_alloc(), the variable rh is not freed or passed out if handler is NULL, which     could lead to a memleak, fix it.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1782151303 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: fix memory leak     when blob is malformed The bug fix was incomplete, it replaced crash with a memory leak. The old code     had an assignment to ret embedded into the conditional, restore this. (CVE-2022-48641)

  - In the Linux kernel, the following vulnerability has been resolved: thermal/int340x_thermal: handle     data_vault when the value is ZERO_SIZE_PTR In some case, the GDDV returns a package with a buffer which     has zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10). Then the data_vault_read() got     NULL point dereference problem when accessing the 0x10 value in data_vault. [ 71.024560] BUG: kernel NULL     pointer dereference, address: 0000000000000010 This patch uses ZERO_OR_NULL_PTR() for checking     ZERO_SIZE_PTR or NULL value in data_vault. (CVE-2022-48703)

  - In the Linux kernel, the following vulnerability has been resolved: ice: switch: fix potential memleak in     ice_add_adv_recipe() When ice_add_special_words() fails, the 'rm' is not released, which will lead to a     memory leak. Fix this up by going to 'err_unroll' label. Compile tested only. (CVE-2022-48709)

  - In the Linux kernel, the following vulnerability has been resolved: xen-netfront: Fix NULL sring after     live migration A NAPI is setup for each network sring to poll data to kernel The sring with source host is     destroyed before live migration and new sring with target host is setup after live migration. The NAPI for     the old sring is not deleted until setup new sring with target host after migration. With     busy_poll/busy_read enabled, the NAPI can be polled before got deleted when resume VM.

  - In the Linux kernel, the following vulnerability has been resolved: cifs: fix small mempool leak in     SMB2_negotiate() In some cases of failure (dialect mismatches) in SMB2_negotiate(), after the request is     sent, the checks would return -EIO when they should be rather setting rc = -EIO and jumping to neg_exit to     free the response buffer from mempool. (CVE-2022-49938)
