CVE-2023-53133

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Fix an infinite loop error when len is 0 in tcpbpfrecvmsgparser When the buffer length of the recvmsg system call is 0, we got the flollowing soft lockup problem: watchdog: BUG: soft lockup - CPU3 stuck for 27s!...

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...
