CVE-2026-74705

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the tunnel segmentation process. The function skb udp tunnel segment() retrieves the UDP header before confirming the tunnel header is in the skb head. If the pull operation reallocates skb->head, the previously saved UDP header pointer becomes invalid, leading to a potential use-after-free condition.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
