Kernel privilege escalation via GPU page-table corruption
Published Aug 5, 2024 · Updated Aug 5, 2024
Improper access control in Qualcomm Snapdragon GPU drivers allows local users to gain kernel privileges by corrupting GPU page tables. The a6xx_protect_init path fails to prevent a user-space graphics client from corrupting page-table entries that govern DDR access. Successful exploitation requires local code execution on an affected Snapdragon implementation and grants kernel-level memory access.

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.
