Local compromise via shared-key import memory corruption
Published Aug 5, 2024 · Updated Aug 15, 2024
Memory corruption in Qualcomm Snapdragon keymaster firmware allows local users to compromise confidentiality, integrity, and availability. A keymaster operation corrupts memory while importing a shared key, but Qualcomm has not disclosed the affected routine or erroneous bounds operation. Exploitation requires local low-privileged access and no user interaction; the documented consequence spans device data, execution integrity, and service availability.
