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...

CVE-2026-80840

In the Linux kernel, the following vulnerability has been resolved: ipv6: seg6: clear IPv4 control block on IPIP decapsulation End.DX4 and End.DT4 decapsulate an IPv4 packet through decapandvalidate and send it directly to IPv4 routing. The inner packet therefore bypasses iprcvcore, which normall...
