medium Tenable Cloud Security Plugin ID 457409

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - Fix incorrect boolean
 values in af_alg_ctx Commit 1b34cbbf4f01 ("crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg")
 changed some fields from bool to 1-bit bitfields of type u32. However, some assignments to these fields,
 specifically 'more' and 'merge', assign values greater than 1. These relied on C's implicit conversion to
 bool, such that zero becomes false and nonzero becomes true. With a 1-bit bitfields of type u32 instead,
 mod 2 of the value is taken instead, resulting in 0 being assigned in some cases when 1 was intended. Fix
 this by restoring the bool type. (CVE-2025-40022)

Solution

Update the linux library and its related packages to version 6.1.158-1 or later.
