Linux Kernel Time-of-Check Time-of-Use (TOCTOU) Race Condition Vulnerability

Linux kernel contains a time-of-check time-of-use (TOCTOU) race condition vulnerability that has a high impact on confidentiality, integrity, and availability.

Added to KEV: 2025-09-04Federal patch deadline: 2025-09-25

Required Action (CISA)

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Risk Analysis

This high-severity time-of-check time-of-use (TOCTOU) race condition vulnerability in the Linux kernel has a high impact on confidentiality, integrity, and availability. Such flaws can be difficult to reliably exploit but can lead to severe system compromise. The confirmed exploitation by CISA (is_in_kev: true) highlights its critical nature.

Active exploitation of this vulnerability has been observed in the wild. This indicates that attackers have developed reliable methods to exploit this race condition.

Recommended Action

Apply the latest security updates and patches for the Linux kernel. Regularly update operating systems to address complex kernel vulnerabilities like TOCTOU race conditions.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2025-38352 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2025-38352 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
