CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2022-48919 – cifs: fix double free race when mount fails in cifs_get_root()
https://notcve.org/view.php?id=CVE-2022-48919
In the Linux kernel, the following vulnerability has been resolved: cifs: fix double free race when mount fails in cifs_get_root() When cifs_get_root() fails during cifs_smb3_do_mount() we call deactivate_locked_super() which eventually will call delayed_free() which will free the context. In this situation we should not proceed to enter the out: section in cifs_smb3_do_mount() and free the same resources a second time.
