NVD Description

Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

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

eventpoll: defer struct eventpoll free to RCU grace period

In certain situations, ep_free() in eventpoll.c will kfree the epi->ep eventpoll struct while it still being used by another concurrent thread. Defer the kfree() to an RCU callback to prevent UAF.
