CVE-2026-80976
CVE-2026-80976 is a Linux kernel vulnerability in the seg6 (SRv6) decapsulation path . After decap_and_validate() strips outer Segment Routing headers, the IPv6 control block (IP6CB) retains a stale nhoff offset from the outer packet. When the inner IPv6 packet is delivered via ip6_protocol_deliv...

CVE-2026-80840
CVE-2026-80840 is a slab-out-of-bounds write in the Linux kernel IPv6 Segment Routing (seg6) code. When End.DX4 or End.DT4 decapsulates an inner IPv4 packet via decap_and_validate(), the skb retains stale IP6CB data that overlaps with IPCB fields. A crafted outer Destination Options header sets o...
