Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> cachestat: do not flush stats in recency check<br /> <br /> syzbot detects that cachestat() is flushing stats, which can sleep, in its<br /> RCU read section (see [1]). This is done in the workingset_test_recent()<br /> step (which checks if the folio&amp;#39;s eviction is recent).<br /> <br /> Move the stat flushing step to before the RCU read section of cachestat,<br /> and skip stat flushing during the recency check.<br /> <br /> [1]: https://lore.kernel.org/cgroups/000000000000f71227061bdf97e0@google.com/
