Memory corruption via concurrent fence use-after-free
Published Apr 6, 2026 · Updated Apr 6, 2026
Use-after-free in the Qualcomm Snapdragon camera driver allows local users to corrupt memory through concurrent fence operations. Concurrent fence deregistration can free a fence while signal handling still accesses it, causing memory corruption. Exploitation requires local low-privileged access and winning the race; Qualcomm has not disclosed the exact post-corruption outcome.
