Description OSIDB Bzimport 2026-05-06 13:02:40 UTC 
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.
