Use after free in Digital Credentials in Google Chrome prior to 149.0.7827.155 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Heap corruption in Google Chrome's Digital Credentials component (versions prior to 149.0.7827.155) allows remote attackers to trigger a use-after-free condition by enticing a user to visit a crafted HTML page, potentially leading to arbitrary code execution within the renderer process. Chromium rates this issue as Critical severity, and Google has released a patched stable-channel build; no public exploit identified at time of analysis and EPSS sits at 0.31% (23rd percentile), indicating low predicted near-term exploitation pressure despite the high CVSS of 8.8.

Technical ContextAI

The flaw resides in Chrome's Digital Credentials API, the browser surface that lets websites request verifiable credentials (e.g., mobile driver's licenses, identity wallets) through the navigator.credentials interface backed by Chromium's content/browser credential management code. CWE-416 (Use After Free) means an object in the Digital Credentials handler is freed while a reference to it remains live; subsequent dereference operates on attacker-influenceable heap memory, enabling heap layout manipulation that can be steered toward type confusion or control-flow hijack. The affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* across all platforms shipping the Blink/Chromium renderer, and exploitation primitives in this subsystem typically execute inside the sandboxed renderer process - meaningful code execution outside the sandbox requires a separate sandbox-escape bug to chain.

RemediationAI

Vendor-released patch: update Google Chrome to 149.0.7827.155 or later on Windows, macOS, and Linux via the stable channel update described in https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_01750511403.html; managed environments should force-push the update through Chrome Browser Cloud Management, Group Policy (RelaunchNotificationPeriod), or Jamf/Intune and verify by checking chrome://settings/help on endpoints. Operators of downstream Chromium-based browsers should apply the equivalent vendor build once it incorporates the Chromium milestone fix. Until patches are deployed, a targeted compensating control is to disable the Digital Credentials API surface where feasible - Chrome exposes this behind enterprise policy and origin-trial gating, so administrators can restrict it via the DigitalCredentialsEnabled-style policy or block the relevant origin trial tokens, accepting the trade-off that any legitimate identity-wallet flows will break.
