Userspace can trigger a NULL pointer\ndereference from any render-node fd by submitting an execbuf with\ndx_context_handle == SVGA3D_INVALID_ID and a SVGA_3D_CMD_DX_BIND_QUERY\nopcode in the command stream: dx_ctx_node is left NULL and the kernel\noopses on the assignment.  The same NULL is then re-read in\nvmw_resources_reserve() via vmw_context_get_dx_query_mob().\n\nAll sibling DX handlers fail-close on a missing dx_ctx_node using\nVMW_GET_CTX_NODE().  Use the same pattern here, returning -EINVAL up\nfront before any relocation state is published.","published":"2026-08-15T13:17:49.000Z","lastModified":"2026-08-17T06:19:40.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00168,"percentile":0.06055,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
