Local code execution via JPEG Encoder IOCTL race
Published Nov 4, 2024 · Updated Nov 16, 2024
Memory corruption in Qualcomm Snapdragon JPEG Encoder driver firmware allows local users to execute code through crafted IOCTL calls. A time-of-check time-of-use race lets an IOCTL-supplied object change between validation and use, corrupting memory in the JPEG Encoder path. Low-privileged local access is required; successful exploitation can read, alter, or interrupt data and execution within the affected component.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
