CVE-2026-20731
MediumCVSS 6.1Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
Improper buffer restrictions in Intel NPU Driver for user applications (Ring 3) may allow denial of service. An unprivileged attacker with an authenticated user and a low complexity attack can cause system unavailability via local access, without user interaction.
Risk Assessment
Risk of system downtime due to denial of service, potentially affecting service availability.
Recommendation
Update Intel NPU Driver to the latest version with security fixes.
Other vulnerabilities in Intel NPU Driver
See all- CVE-2026-20908Medium
A Time-of-check time-of-use race condition in the Intel(R) NPU Driver for Windows may allow a denial of service. An attacker with an authenticated user and a high complexity attack may cause a denial of service. The attack requires local access, no user interaction, and may impact integrity and availability.
- CVE-2026-20786Medium
Out-of-bounds read in the Intel(R) NPU Driver may allow a denial of service. An attacker with an authenticated user and a low complexity attack may cause a denial of service. The attack requires local access, no user interaction, and may impact integrity and availability.
- CVE-2026-20783Medium
Improper conditions check in the firmware for the Intel(R) NPU Driver may allow a denial of service. An attacker with an authenticated user and a low complexity attack may cause a denial of service. The attack requires local access, no user interaction, and may impact integrity and availability.
- CVE-2026-20769Medium
Improper conditions check in Intel(R) NPU Driver for all versions within Ring 3: User Applications may allow a denial of service. The attack requires an authenticated user, low complexity, and local access, with no user interaction. The vulnerability impacts integrity (low) and availability (high), but not confidentiality.
Original NVD description (English source)
Improper buffer restrictions for the Intel(R) NPU Driver for all versions within Ring 3: User Applications may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
