Local radio service crash via unchecked null pointer
Published Apr 16, 2020 · Updated Aug 5, 2024
Null pointer dereference in Qualcomm Snapdragon radio interface layers allows local users to crash the radio service on affected chipsets. The sapmodule destructor dereferences a pointer without first checking whether it is null, terminating the radio interface layer when that invalid state is reached. Low-privileged local access is required, and the resulting service interrupt has no reported confidentiality or integrity impact.
