Local memory corruption via queued sync object destruction
Published Mar 5, 2020 · Updated Aug 5, 2024
Use-after-free in Qualcomm Snapdragon graphics on affected chipsets allows local users to corrupt memory through a sync-object error path. During error handling, the graphics module destroys a synchronization object that has already been queued, leaving queued work able to reference freed storage. Local access to an affected chipset is required; Qualcomm does not disclose whether exploitation yields code execution, data access, or a crash.
