A race condition vulnerability exists in the FileSystem component of Google Chrome versions prior to 153.0.8010.52. This flaw allows a remote attacker, who has already compromised the renderer process and used social engineering, to bypass system access restrictions via a crafted HTML page. The Chromium project has assigned this issue a medium severity rating. No CVSS score is provided, and no explicit patch or remediation information is included in the available data.
AI Analysis
Technical Summary
CVE-2026-93380 describes a race condition in the FileSystem implementation of Google Chrome before version 153.0.8010.52. Exploitation requires prior compromise of the renderer process and social engineering to deliver a malicious HTML page that bypasses system access controls. The vulnerability is classified as CWE-367 (Time-of-check Time-of-use race condition). The Chromium security team rates this as medium severity. No detailed technical or patch information is provided in the source data.
Potential Impact
An attacker who has already compromised the renderer process can leverage this race condition to bypass system access restrictions, potentially escalating privileges or accessing restricted resources. The impact is limited by the prerequisite of renderer compromise and social engineering, reducing the overall risk profile to medium severity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability affects versions prior to 153.0.8010.52, updating to version 153.0.8010.52 or later is likely recommended once official guidance is available.
