CVE-2021-30313

Memory corruption via concurrent folder operations

Published Jan 13, 2022 · Updated Aug 3, 2024

Use-after-free in Qualcomm Snapdragon wired connectivity allows local users with high privileges to corrupt memory through a folder race. Concurrent folder creation and deletion can release an object while another execution path still uses it; Qualcomm has not identified the affected function or object. Exploitation requires local, high-privilege access and no user interaction, while the resulting consequence beyond memory corruption remains undisclosed.
