CVE-2022-49889

In CVE-2022-49889, the Linux kernel ring-buffer wake path could dereference a NULL or invalid buffer when waking waiters during ring-buffer shutdown on systems where listed CPUs > online CPUs. The fix adds a NULL check for the buffer and validates the allocation against online CPUs; it also no...
