CVE-2023-53133

CVE-2023-53133 affects the Linux kernel’s BPF sockmap path (tcp_bpf_recvmsg_parser) where a 0-length recvmsg can loop indefinitely. The description and connected advisories confirm the root cause is an infinite loop when len is 0 and that the fix is to return 0 for length 0 in tcp_bpf_recvmsg_par...

CVE-2023-53111

CVE-2023-53111 affects the Linux kernel loop subsystem. The vulnerability arises from a use-after-free in loop_handle_cmd() after do_req_filebacked() completes, which may dereference cmd or rq depending on whether the request was completed when using asynchronous I/O. The issue can lead to a kern...
