"value": "AV:L - The flaw is reached through a local read() on the MOTU ALSA hwdep device; there is no network-receive path, although a supported FireWire unit must be attached and streaming.\nAC:L - The caller can deterministically trigger the overrun by supplying a count greater than the 8-byte header but not divisible by four while a DSP event is queued. No race or condition outside the attacker's control is required.\nPR:L - No capability or authentication check exists in the hwdep path; the attacker only needs ordinary user access to the sound device, commonly granted through an active-seat ACL or audio-group membership.\nUI:N - The attacker can open the hwdep and PCM devices, start streaming, and issue the malformed read without action by another user.\nS:U - The overwrite affects memory associated with the local consuming process and does not cross a VM, IOMMU, container, or other security-authority boundary.\nC:N - The vulnerable operation only writes an initialized DSP event to userspace; it performs no out-of-bounds read and provides no kernel-memory disclosure primitive.\nI:H - The loop can write a complete 32-bit, device-influenced event when only one to three bytes remain, corrupting adjacent userspace control data. Under the required higher-severity treatment for an out-of-bounds write, integrity impact is High.\nA:H - The adjacent-memory corruption can terminate the consuming process or a critical audio or control service and can be triggered repeatedly. Under the required higher-severity treatment for any crash, availability impact is High."
