CVE-2026-98949 at MITRE

Description

In the Linux kernel, the following vulnerability has been resolved:

drm/imagination: Fix reference and vm_bo handling in remap()

When a map overlaps part of an existing mapping, pvr_vm_gpuva_remap()
splits the mapping into prev/next parts covering what the request did
not take, instead of creating something new. It gets two things wrong.

- A GEM reference is taken for each part but it's never needed and never
dropped, so it leaks one reference per split (remap-next-in-2m in
tests/imagination/pvr_vm_map.c):

CRITICAL: 33558528 bytes of shmem still held after close

- The parts still belong to the original object being split, but
pvr_vm_gpuva_remap() links them to ctx->gpuvm_bo, the new object's
vm_bo:

prev_va --obj--> BO_A BO_B <--obj-- vm_bo (ctx->gpuvm_bo)
\___________link___________/ (mismatch: BO_A != BO_B)

drm_gpuva_link() catches the mismatch:

WARNING: drivers/gpu/drm/drm_gpuvm.c:2108 at drm_gpuva_link+0x2ec/0x310
drm_WARN_ON(obj != vm_bo->obj)
Call trace:
drm_gpuva_link
pvr_vm_gpuva_remap
__drm_gpuvm_sm_map
pvr_vm_map
pvr_ioctl_vm_map

Link them to op->remap.unmap->va->vm_bo instead.

The locking of the GPUVA lists of the other objects touched by a split is
not addressed here; it is handled by switching the GPUVM to immediate
mode.
