Vulnerability Details CVE-2024-41033
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.
