Kernel code execution via unchecked firmware addresses
Published Sep 11, 2024 · Updated Sep 13, 2024
Out-of-bounds write in Imagination PowerVR GPU DDK 24.1 and earlier allows local users to execute code with kernel privileges. PVRSRVBridgeRGXKickTA3D2 accepts improper GPU system-call data, allowing unchecked firmware addresses to reach PVRSRVRGXKickTA3DKM and be written outside the intended kernel buffer. A nonprivileged application with local driver access is sufficient; no user interaction is required, and successful exploitation gains kernel execution.

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.
