CVE-2026-87578: Use after free in Google Chrome
Use after free in Receiver in Google Chrome prior to 153.0.8010.36 allowed an adjacent attacker to execute arbitrary code outside the sandbox via crafted network traffic. (Chromium security severity: High)
AI Analysis
Technical Summary
CVE-2026-87578 is a use-after-free vulnerability (CWE-416) in the Receiver component of Google Chrome before version 153.0.8010.36. An attacker with adjacent network access can exploit this flaw by sending specially crafted network traffic, resulting in arbitrary code execution outside the sandbox environment. This vulnerability could allow code execution with elevated privileges relative to the sandbox. There is no public information on active exploitation or available patches at this time.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker on an adjacent network to execute arbitrary code outside the Chrome sandbox, potentially compromising the security boundaries of the browser and the underlying system. This elevates the risk of system compromise or data breach if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should exercise caution with untrusted network environments and monitor for updates from Google Chrome regarding this vulnerability.
