linux: An issue was discovered in the Linux kernel 5.10.x before 5.10.155
CVE-2022-47946 is fixed in linux on 1 platform, first by DEBIAN-CVE-2022-47946, released December 23, 2022. It is not reported as exploited. Patch Radar priority: Routine.
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.
