CVE-2022-49207

CVE-2022-49207 is a Linux kernel vulnerability in the bpf/sockmap path (sk_psock_queue_msg memleak). The issue occurs when tcp_bpf_sendmsg runs during tear down, causing memory charged by sk_mem_charge to remain outstanding as messages are queued, potentially leading to memory leaks. The provided...
