Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2026-06-01 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

cifs: Fix connections leak when tlink setup failed

If the tlink setup failed, lost to put the connections, then the module refcnt leak since the cifsd kthread not exit.

Also leak the fscache info, and for next mount with fsc, it will print the follow errors: CIFS: Cache volume key already in use (cifs,127.0.0.1:445,TEST)

Let's check the result of tlink setup, and do some cleanup.

Severity

5.5 (Medium)
