CVE-2026-64057

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

Description The afs filesystem in the kernel implements incorrect locking for symbolic links. This leads to several issues, including a lack of locking around the afs read single() function, which can cause races between multiple get link() calls and result in leaks. Additionally, the system fails to use RCU barriering when accessing buffer pointers during RCU pathwalk and may race with other threads when a third party updates symlink contents on the server.

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