CVE-2022-50865

CVE-2022-50865: In the Linux kernel, signed integer overflow can occur in tcp_add_backlog() when calculating backlog limits from sk_rcvbuf, sk_sndbuf, and 64*1024. The fix reduces the limit by halving sndbuf, addressing potential backlog miscalculation and TCP behavior under certain workloads. Co...
