Host memory corruption via mutable guest buffer
Published May 6, 2025 · Updated Feb 26, 2026
Memory corruption in Qualcomm Snapdragon Auto automotive QNX software allows guest OS users to corrupt memory through a controlled message buffer. The message-processing path consumes a Guest VM-controlled buffer whose value can change continuously during processing, so validation does not stabilize the data before use. A low-privileged local guest is required; Qualcomm has not disclosed whether the resulting corruption yields code execution, data access, or a service crash.
