CVE-2026-80905

A flaw was found in the kernel. When processing VLAN-tagged frames, the network header is incorrectly advanced past the VLAN tag before the transport header is probed. This misinterprets the inner protocol header as a VLAN header, resulting in an uninitialized transport header. This issue can lea...
