io_uring UAF, Unix SCM garbage collection
A flaw was found in the Linux kernel. A race issue occurs between an io_uring request and the Unix socket garbage collector, allowing an attacker local privilege escalation.
Отчет
Red Hat Enterprise Linux is not affected by this flaw as io_uring (CONFIG_IO_URING) is not enabled in any current shipping kernels.
