CVE-2026-98299

The Linux kernel is vulnerable to a division by zero crash in the tcp_rcvbuf_grow() and tcp_rcv_space_adjust() functions within net/ipv4/tcp_input.c. The root cause is that if net.ipv4.tcp_rmem is configured with arbitrarily small values (e.g., 1), sk->sk_rcvbuf is initialized to 1, causing tp...
