CVE-2026-31619
Estado: ModificadaMedia (5.5)—
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.
CVSS
