An issue was discovered in the Linux kernel 5.10.x before 5.10.155. A
use-after-free in io_sqpoll_wait_sq in fs/io_uring.c allows an attacker to
crash the kernel, resulting in denial of service. finish_wait can be
skipped. An attack can occur in some situations by forking a process and
then quickly terminating it. NOTE: later kernel versions, such as the 5.15
longterm series, substantially changed the implementation of
io_sqpoll_wait_sq.
