Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: eventpoll: Fixed an UAF Use-After-Free issue with epremovestruct eventpoll and struct file. The epremove function via epremovefile clears the file-fep field under file-flock, but then continues using @file within the critical...

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...
