"value": "AV:L - The flaw is reached when the on-chip SOF DSP delivers IPC4 MODULE_NOTIFICATION messages to the host via mailbox/IRQ; exploitation requires local access to a SOF-equipped system using the ALSA control interface, not remote network delivery.\nAC:L - A local attacker can repeatedly issue ALSA control ioctls that cause the DSP to emit control-change notifications; no race or victim state beyond attacker-driven audio IPC is needed to supply inconsistent num_elems versus event_data_size.\nPR:L - Only an unprivileged local user able to open ALSA control devices on SOF hardware (typical on Intel laptop/desktop audio stacks) is required; root or init-namespace capabilities are not needed to drive the vulnerable notification path.\nUI:N - No action by a separate victim is required; the attacker triggers DSP notifications through their own ALSA control operations and the kernel processes malformed firmware payloads automatically.\nS:U - Impact stays within the host kernel audio subsystem on the same machine; heap disclosure or control-cache corruption does not cross VM, container, or IOMMU boundaries into another security authority.\nC:H - Missing payload-length validation lets num_elems drive memcpy and chanv parsing beyond the kmalloc IPC notification buffer, causing out-of-bounds kernel heap reads that can disclose adjacent memory contents.\nI:H - Untrusted num_elems values cause kernel memory corruption by copying out-of-bounds firmware/heap bytes into control caches via memcpy and chanv updates, providing bounded but attacker-influenced kernel writes usable in further exploitation.\nA:H - Large num_elems values trigger extensive out-of-bounds accesses during IRQ-threaded IPC notification handling, which can provoke KASAN faults, unhandled page faults, kernel oops, or panic under realistic SOF workloads."
