CVE-2026-80978

CVE-2026-80978 affects the Linux kernel networking subsystem, specifically the IP tunnel devices. When a local attacker stacks user-created IP tunnel devices, the derived needed_headroom can exceed the 16-bit skb header offset range, causing those offsets to wrap during skb head expansion. The fi...
