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...

CVE-2026-74640

This is an out-of-bounds write in the Linux kernel's ALSA FCP (FireWire Control Protocol) driver, specifically in fcp_meter_ctl_get(). The root cause is a mismatch: fcp_ioctl_set_meter_map() permits a Level Meter map size up to 255 , but the destination buffer struct snd_ctl_elem_value declares l...
