CVE-2022-2602

CVE-2022-2602 is a Linux kernel vulnerability in io_uring related to a use-after-free in the Unix garbage collection path. Multiple connected sources confirm a local, kernel-side issue (io_uring UAF) that can be exploited to crash the kernel and, in PoC scenarios, enable privilege escalation by r...
