Exploiting CVE-2024-50264: A Race Against Time in the Linux Kernel

This article details the author's journey exploiting the complex CVE-2024-50264 Linux kernel vulnerability using their kernel-hack-drill project. The vulnerability, a challenging race condition, presented numerous obstacles, including a UAF write occurring microseconds after kfree(), hindering cross-cache attacks. The author cleverly utilized the 'immortal' signal 33 to interrupt the connect() syscall, combined with a cross-cache attack and a novel msg_msg spraying technique, ultimately bypassing limitations and achieving privilege escalation. This challenging exploit showcases advanced reverse engineering and exploitation skills, highlighting the value of kernel-hack-drill in vulnerability research.
