CVE-2020-11254

Local service interrupt via unchecked session pointer

Published May 7, 2021 · Updated Aug 4, 2024

NULL-pointer dereference in the Qualcomm Snapdragon Camera component allows local users to interrupt it during buffer allocation. The Camera allocation path dereferences its session context without first checking whether the pointer is valid, causing memory corruption when it is null. Local access is required, and the published impact is limited to availability, with no reported data disclosure or modification.
