kernel: eventpoll: defer struct eventpoll free to RCU grace period

A flaw was found in the Linux kernel's eventpoll component. In certain situations, the epfree function in eventpoll.c can prematurely free the eventpoll data structure while it is still being used by another concurrent thread. This use-after-free UAF vulnerability could allow a local attacker to...

kernel: eventpoll: fix ep_remove struct eventpoll / struct file UAF

A flaw was found in the Linux kernel's eventpoll mechanism. A Use-After-Free UAF vulnerability, where the system attempts to access memory after it has been freed, can occur during the removal of a file. A local attacker could exploit this race condition to corrupt memory, potentially leading to...
