A use-after-free flaw was found in the io_uring subsystem of the Linux kernel. This issue occurs during the IORING_OP_SPLICE operation due to a missing IO_WQ_WORK_FILES flag, leading to an invalid decrease of its reference counter and later causing the use-after-free vulnerability. This flaw allows a local user to crash or potentially escalate their privileges on the system.
