CVE-2026-74480

CVE-2026-74480 affects the Linux kernel networking bridge code. The fast-leave path in br_multicast_leave_group() can dereference a stale mp->ports entry after br_multicast_del_pg() removes a port group, enabling a scenario where multiple port groups for the same port/group with different sour...

EUVD-2026-59671

In the Linux kernel, the following vulnerability has been resolved: um: vector: fix use-after-free in vectormmsgrx When vectormmsgrx discards a packet whose overlay header fails verifyheader, it frees the skb and continues the loop: if headercheck estats.rxencapserrors++; continue; The normal and...

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...
