Chromium CVE-2026-95344: Race Condition in DevTools Affects Microsoft Edge
A race condition in Chromium's DevTools (CVE‑2026‑95344) can allow attackers to exploit timing issues during debugging sessions. The flaw is present in all Chromium‑based browsers, including Microsoft Edge, until the latest update. Defenders should verify that Edge is updated to the most recent release and monitor for any abnormal DevTools activity.
What happened
A race condition was discovered in Chromium’s DevTools that can be triggered during debugging sessions. The flaw, identified as CVE‑2026‑95344, allows an attacker to manipulate the timing of internal operations, potentially leading to privilege escalation or arbitrary code execution.
Impact
The vulnerability is present in all Chromium‑based browsers, including Microsoft Edge, until the latest security patch is applied. Users who run outdated versions are susceptible to exploitation if an attacker can gain access to a debugging session.
Mitigation
Update Microsoft Edge to the newest available release. Edge automatically incorporates the Chromium patch that resolves the race condition. If immediate update is not possible, disable DevTools for untrusted contexts or restrict access to the debugging interface.
Monitoring
Watch for unusual DevTools activity, such as repeated or rapid opening of debugging panels, and verify that no unauthorized scripts are injected into the debugging environment.
