CVE-2026-31619
概要

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

ALSA: fireworks: bound device-supplied status before string array lookup

The status field in an EFW response is a 32-bit value supplied by the
firewire device. efr_status_names[] has 17 entries so a status value
outside that range goes off into the weeds when looking at the %s value.

Even worse, the status could return EFR_STATUS_INCOMPLETE which is
0x80000000, and is obviously not in that array of potential strings.

Fix this up by properly bounding the index against the array size and
printing "unknown" if it's not recognized.
