CVE-2026-33270 · Severity: info · Published 2026-11-10

Intel Graphics Software contains an improper input validation vulnerability in user-facing applications that allows an attacker to cause a denial of service (system crash or hang). An authenticated local attacker with low privilege can trigger this without special knowledge, causing system unavailability until the system is restarted.

Technologies: [Intel Arc Graphics Driver](https://junglewise.ai/threats/technologies/arc-graphics-driver), [Intel Arc Pro Graphics Driver](https://junglewise.ai/threats/technologies/arc-pro-graphics-driver). Vendors: [Intel](https://junglewise.ai/threats/vendors/intel).
