Description

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

dm-verity: correctly handle dm_bufio_client_create() failure

If either of the calls to dm_bufio_client_create() in verity_fec_ctr() fails, then dm_bufio_client_destroy() is later called with an ERR_PTR() argument. That causes a crash. Fix this.
