Use-after-free sandbox escape in Google Chrome DigitalCredentials

IdentifiersCVE-2026-12008CWE-416· Use After Free

CVE-2026-12008 is a critical use-after-free vulnerability in the DigitalCredentials component of Google Chrome prior to version 149.0.7827.115. According to the provided advisory text, a remote attacker who had already compromised the renderer process could trigger the flaw via a crafted HTML page and potentially escape Chrome’s sandbox. The issue is described as a memory-lifetime error in DigitalCredentials where freed memory may be reused, creating a path to security boundary bypass from a compromised renderer context.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation could allow an attacker who already achieved renderer-process compromise to escape the Chrome sandbox. This could enable execution beyond the renderer’s intended isolation boundary and may lead to further arbitrary code execution, broader access to the host, or additional post-exploitation actions depending on the target environment.

Mitigation

If you can’t patch tonight, do this now.

No specific workaround or temporary mitigation was provided in the supplied advisories. The practical mitigation is to apply the vendor security update promptly. Until patching is completed, reducing exposure to untrusted web content may lower risk, but this is not a vendor-provided fix.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome to version 149.0.7827.115 or later. For Debian chromium, apply the vendor security update and upgrade to 149.0.7827.114-1~deb12u1 on Debian oldstable (bookworm) or 149.0.7827.114-1~deb13u1 on Debian stable (trixie), as provided in the advisory context.
