Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.12.82/6.18.23/6.19.13/7.0.0. Affected is the function efr_status_names of the component ALSA. The impact remains unknown. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2026-31619 since 03/09/2026. Technical details are known, but there is no available exploit.
