CNA vs NVD score

NVD

CNA · qualcomm
8.6
NVD has not scored this yet; the score shown is the CNA’s.

The score given by the assigning authority versus NVD’s independent score. A gap means the severity is contested.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Jun 3, 2025. That signals real attacks, not theory.

Remediation deadline for government agencies: Jun 24, 2025.
