Host interruption via leaked GPU mapping objects
Published Sep 18, 2024 · Updated May 11, 2026
A memory leak in the Linux kernel 6.8 through 6.10.9 allows local users to exhaust memory through repeated GPU virtual-memory changes. The Imagination DRM pvr_vm.c remap and unmap path unlinks a pvr_vm_gpuva allocation without freeing it, retaining small allocations on a high-use code path. Local access that can exercise this path is required; repetition can exhaust kernel memory and interrupt the host.

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.
