medium Tenable Cloud Security Plugin ID 454711

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: jitterentropy - replace long-
 held spinlock with mutex jent_kcapi_random() serializes the shared jitterentropy state, but it currently
 holds a spinlock across the jent_read_entropy() call. That path performs expensive jitter collection and
 SHA3 conditioning, so parallel readers can trigger stalls as contending waiters spin for the same lock. To
 prevent non-preemptible lock hold, replace rng->jent_lock with a mutex so contended readers sleep instead
 of spinning on a shared lock held across expensive entropy generation. (CVE-2026-52936)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.395.138 or later.
