There is no fixed version for RHEL:7 kernel-rt.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt package and not the kernel-rt package as distributed by RHEL.
See How to fix? for RHEL: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.
