CVE-2023-43543

Memory corruption via audio graph use-after-free

Published Jun 3, 2024 · Updated Aug 2, 2024

Use-after-free memory corruption in Qualcomm Audio firmware allows local privileged users to corrupt memory during playback or recording. A race between allocation and deallocation frees an audio graph object while another execution path can still access it. Exploitation requires high local privileges and concurrent audio activity; the published record specifies no consequence beyond memory corruption.
