A fix is available — apply it.

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

smb: client: fix double put of @cfile in smb2_set_path_size()

If smb2_compound_op() is called with a valid @cfile and returned -EINVAL, we need to call cifs_get_writable_path() before retrying it as the reference of @cfile was already dropped by previous call.

This fixes the following KASAN splat when running fstests generic/013 against Windows Server 2022:
