CVE-2026-80816

This Linux kernel vulnerability affects the ALSA FCP (Firmware Configuration Protocol) module. The root cause is that fcp_init_notify() shared a URB (mixer->urb ) with the optional UAC2 status interrupt endpoint . On devices exposing that endpoint, the early-return path fired prematurely, leav...

CVE-2026-74640

A flaw was found in the Linux kernel's ALSA FireWire Control Protocol FCP. An unprivileged process can trigger an out-of-bounds write by reading controls on /dev/snd/controlC0 after an oversized Level Meter map has been installed. This occurs because the fcpmeterctlget function writes beyond its...
