AI Analysis
Technical Summary
CVE-2026-91743 describes a race condition in the Core of Google Chrome before version 153.0.8010.47. An attacker who has compromised the renderer process can exploit this flaw to execute arbitrary code outside the sandbox environment via a specially crafted HTML page. The vulnerability is classified under CWE-367 (Time-of-check Time-of-use Race Condition) and has a CVSS v3.1 base score of 8.3, indicating high severity. No known exploits in the wild have been reported. The vulnerability affects local Chrome installations and is not related to cloud services.
Potential Impact
Successful exploitation allows an attacker with control over the renderer process to execute arbitrary code outside the sandbox, potentially compromising the security boundaries of the browser. This could lead to full system compromise or unauthorized actions beyond the renderer's privileges.
Mitigation Recommendations
A fix is available in Google Chrome version 153.0.8010.47 and later. Users and administrators should update to this version or a more recent release to remediate the vulnerability. No additional mitigation steps are indicated.
