Memory corruption via camera thread cleanup race
Published May 7, 2021 · Updated Aug 4, 2024
Use-after-free in the Qualcomm Snapdragon camera subsystem allows local users to corrupt memory by triggering a cleanup race. The camera thread manager frees processing objects during teardown while a worker thread can still access them. Exploitation requires local low-privileged access and user interaction; Qualcomm does not disclose the resulting behavior beyond memory-safety failure.
