Service interrupt via leaked buffer objects
Published May 28, 2026 · Updated May 28, 2026
A memory leak in the Intel Xe DRM driver in Linux Kernel allows local users to cause a service interrupt through failed dma-buf imports. On an allocation-error path, xe_dma_buf_init_obj() returns without freeing the preallocated storage buffer object after drm_gpuvm_resv_object_alloc() fails. Exposure requires local low-privilege access to the Intel Xe graphics path; repeated failures consume kernel memory until service is interrupted.

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.
