CVE-2026-98853

The Linux kernel contains a vulnerability where IP-in-IP GSO can re-enter inet_gso_segment() or ipv6_gso_segment() for each nested IP header. Because encap_level tracks header bytes instead of callback depth, a deep chain can cause kernel stack exhaustion . To resolve this, the kernel now counts ...
