CVE-2025-1146CrowdStrike Falcon Sensor for Linux TLS Issue
High 8.1
In plain English
A high-severity security flaw in Falcon Container Sensor from CrowdStrike. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 18% of all known vulnerabilities).
Official description
CrowdStrike uses industry-standard TLS (transport layer security) to secure communications from the Falcon sensor to the CrowdStrike cloud. CrowdStrike has identified a validation logic error in the Falcon sensor for Linux, Falcon Kubernetes Admission Controller, and Falcon Container Sensor where our TLS connection routine to the CrowdStrike cloud can incorrectly process server certificate validation. This could allow an attacker with the ability to control network traffic to potentially conduct a man-in-the-middle (MiTM) attack. CrowdStrike identified this issue internally and released a security fix in all Falcon sensor for Linux, Falcon Kubernetes Admission Controller, and Falcon Container Sensor versions 7.06 and above. CrowdStrike identified this issue through our longstanding, rigorous security review process, which has been continually strengthened with deeper source code analysis and ongoing program enhancements as part of our commitment to security resilience. CrowdStrike has no indication of any exploitation of this issue in the wild. CrowdStrike has leveraged its world class threat hunting and intelligence capabilities to actively monitor for signs of abuse or usage of this flaw and will continue to do so. Windows and Mac sensors are not affected by this.
