Kernel compromise via GPU use-after-free
Published Apr 1, 2024 · Updated Aug 12, 2024
Use-after-free in Qualcomm Snapdragon firmware allows local users to corrupt kernel memory while performing GPU operations. Qualcomm has not published the kernel function, lifetime error, or GPU request that leaves the freed object reachable. Local access with no prior privileges is required; successful exploitation compromises kernel confidentiality, integrity, and availability.

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.
