CVE-2026-74263

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

Description A NULL pointer dereference occurs in the t7xx port ctrl tx() function when it fails to verify the result of skb clone(). The function clones each skb fragment before passing it to the port transmit path and immediately attempts to set cloned->len. If the cloning process fails, the resulting NULL pointer is dereferenced, leading to a system crash.

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