Vulnerability from github – Published: 2024-08-17 09:30 – Updated: 2025-11-04 00:31

Details

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

cifs: fix potential null pointer use in destroy_workqueue in init_cifs error path

Dan Carpenter reported a Smack static checker warning: fs/smb/client/cifsfs.c:1981 init_cifs() error: we previously assumed 'serverclose_wq' could be null (see line 1895)

The patch which introduced the serverclose workqueue used the wrong oredering in error paths in init_cifs() for freeing it on errors.

Severity

5.5 (Medium)
