Memory corruption via racy IPC callback reuse
Published Jun 3, 2024 · Updated Aug 2, 2024
Use-after-free in Qualcomm Snapdragon Audio firmware allows local privileged users to corrupt memory through an IPC callback race. During callback registration, one thread releases an IPC callback handle while another thread continues using the stale handle, producing memory corruption. Exploitation requires local high privileges and no user interaction; successful abuse can compromise confidentiality, integrity, and availability.
