CVE-2023-0468

Published: 26 January 2023

A use-after-free flaw was found in io_uring/poll.c in io_poll_check_events in the io_uring subcomponent in the Linux Kernel due to a race condition of poll_refs. This flaw may cause a NULL pointer dereference.

From the Ubuntu Security Team

Lin Ma discovered a race condition in the io_uring subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash).
