Local memory corruption via unreleased EEPROM mutex
Published Jan 21, 2020 · Updated Aug 5, 2024
Use-after-free in Qualcomm Snapdragon camera firmware on listed chipsets allows local users to trigger unsafe reuse of freed memory. During EEPROM query processing, an error path can fail to unlock a mutex, leading camera code to access an object after its memory is freed. Low-privileged local access is required and no user interaction is needed; Qualcomm has not disclosed whether exploitation yields a crash, data access, or code execution.
