"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.    [Thu Feb 10 12:59:06 2022] BUG: KASAN:
