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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0634d50e8b398c25bd07c96b048e484d22688c26","https://git.kernel.org/stable/c/55ec09c9ce10b1272802c7ab6c1be2ea0dbc68db","https://git.kernel.org/stable/c/6af8f0571b4f07e9b102641f195e0ae3cd3a6c71","https://git.kernel.org/stable/c/6b1eb0b63cc153e1c0cb5ab8350950119be11947","https://git.kernel.org/stable/c/7eae011829f94a76470ec76f016805f508437755"],"products":[],"source":"nvd","synced_at":"2026-10-30T13:47:47.119061695+00:00"},"epss":{"cve":"CVE-2026-74445","score":0.00168,"percentile":0.06098,"date":"2026-10-30"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
