CVE-2023-52523

CVE-2023-52523 is a Linux kernel vulnerability where a BPF sockmap/sk_msg redirect can cause a crash if the egress target is a non-TCP socket. The root cause is a hard-coded assumption that the egress socket is TCP; after enabling redirects to non-TCP sockets, a non-TCP target leads to an invalid...
