CVE-2022-49450

CVE-2022-49450 relates to the Linux kernel AF_RXRPC listen() backlog handling. The underlying issue is that the backlog can be configured up to 32, but the preallocation ring has 32 slots and one slot is always dead due to the ring using CIRC_CNT(). This caused an oops on socket close when listen...
