Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
