CVE-2026-64226

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

Description A Use-After-Free (UAF) issue exists in the scx root enable workfn() function during the initialization failure path. The problem occurs because put task struct(p) is called before scx error(), which subsequently attempts to dereference p->comm and p->pid. If the reference held by the iterator is the final drop, the task is freed synchronously, leading to a UAF when the memory is accessed. Use-After-Free is a condition where a program continues to use a pointer after it has been freed, which can lead to crashes or arbitrary code execution.

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