CVE-2026-74500

CVE-2026-74500 affects the Linux kernel’s ALSA usb-audio for RME Digiface. The issue arises when snd_rme_digiface_read_status() reads a four-word status block into an uninitialised on‑stack buffer and, if the vendor IN transfer isn’t negative, copies all four words to status[]. Additionally, snd_...
