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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.
