Kernel compromise via incorrect UNMAP range locking
Published Jun 24, 2026 · Updated Jun 24, 2026
Improper locking in Linux Kernel 6.17 and affected later branches allows local users to compromise kernel confidentiality, integrity, and availability. vm_bind_job_lock_objects passes op->obj_offset instead of op->range to drm_gpuvm_sm_unmap_exec_lock, so non-_NO_SHARE buffer objects involved in UNMAP operations are not always locked. Triggering requires local low-privileged access to the MSM GPU VM_BIND ioctl and a non-_NO_SHARE buffer object, with kernel confidentiality, integrity, and availability at risk.

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.
