Local memory corruption via shared-buffer race
Published Mar 2, 2026 · Updated Mar 2, 2026
Use-after-free in Qualcomm Snapdragon Automotive Audio allows local users to corrupt memory through concurrent shared-buffer IOCTL calls. The Automotive Audio IOCTL path permits concurrent access to a shared buffer and continues using the buffer after another operation frees it. Low-privileged local access is required, and Qualcomm does not specify whether exploitation results in code execution, data access, or a crash.
