Local memory corruption via audio resource mismanagement
Published Mar 5, 2020 · Updated Aug 5, 2024
Use-after-free in Qualcomm Snapdragon audio firmware allows local users to trigger memory corruption through insufficient resource control. The public advisories identify the audio component and deficient resource control, but do not disclose the function, input, or object-lifetime sequence that leaves freed memory reachable. Exploitation requires local low-privileged access on a device using an affected chipset; the reported consequence is bounded to memory corruption because no more specific impact is public.
