CVE-2023-21652

Protected-data compromise via uncleared derived keys

Published Aug 8, 2023 · Updated Oct 11, 2024

Key management errors in Qualcomm Snapdragon HLOS firmware allow local users to read or alter protected information through exposed derived keys. The cryptographic code leaves derived encryption and decryption keys on the stack after use instead of clearing that sensitive memory. Exploitation requires local access to an affected device; disclosure or reuse of the residual keys compromises confidentiality and integrity, not availability.
