CVE-2026-89802

CVE-2026-89802 is a NULL pointer dereference in the drm/nouveau/uvmm driver of the Linux kernel . When a NOUVEAU_VM_BIND job contains an OP_MAP_SPARSE operation that is processed successfully, op->ops remains NULL because the sparse-map path only creates a region without allocating ops. If a s...
