Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • Yes, if you run Qualcomm Multiple Chipsets. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-06-03, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-06-24; treat that as the outer limit, not the target.
  • EPSS 0.5%, percentile 39: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 39% of all scored CVEs (low). EPSS is a probability, not a verdict.
  • Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.

What it is
