CVE-2026-31677

The CVE-2026-31677 issue affects the Linux kernel af_alg path. The root cause is that af_alg_get_rsgl() could extract RX scatterlist data beyond the remaining receive budget, allowing a local attacker to trigger a DoS via recvmsg when there isn’t enough RX space for a chunk. The fix tightens budg...
