CVE-2026-74478

CVE-2026-74478 affects the Linux kernel, specifically the vector_mmsg_rx() path. When a packet is discarded because verify_header() fails, the code previously continued without advancing the slot, leaving a freed skb in the vector and causing a use-after-free in the RX path. The issue can be trig...
