Dangling-pointer access via uncleared freed buffer
Published Feb 7, 2020 · Updated Aug 5, 2024
Use-after-free in Qualcomm Snapdragon Diag Services allows local users to access a dangling pointer after a buffer is freed. The service frees a buffer without setting its pointer to NULL, permitting later access or a second free through the stale reference. Local low-privilege access is required, and public sources do not specify the final consequence beyond dangling-pointer access.
