How to fix?

There is no fixed version for Centos:7 kernel-tools-libs.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-tools-libs package and not the kernel-tools-libs package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

cachestat: do not flush stats in recency check

syzbot detects that cachestat() is flushing stats, which can sleep, in its RCU read section (see 1). This is done in the workingset_test_recent() step (which checks if the folio's eviction is recent).

Move the stat flushing step to before the RCU read section of cachestat, and skip stat flushing during the recency check.
