Use after free in Glic in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Remote code execution in Google Chrome versions prior to 149.0.7827.53 stems from a use-after-free flaw in the Glic component, allowing a remote attacker to run arbitrary code within the renderer sandbox by luring a victim to a crafted HTML page. Google has rated the Chromium security severity as High, and a vendor patch is available, though no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.

Technical ContextAI

The flaw resides in Glic, a Chrome component shipped in Chromium-based browsers built on the Blink rendering engine and V8 JavaScript runtime. CWE-416 (Use After Free) occurs when memory is referenced after it has been deallocated, typically through dangling pointers in C++ object lifecycles; in a renderer context this commonly arises from mismatched object ownership during asynchronous DOM, IPC, or feature-state transitions. Successful exploitation corrupts the heap inside the renderer process, which Chrome confines through its multi-process sandbox, so arbitrary code execution is initially constrained to the sandboxed renderer rather than the host OS unless chained with a sandbox escape.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 or later on the stable desktop channel - upgrade immediately via the built-in updater or by redeploying managed installers, referencing the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. Administrators of Chromium-based browsers should track and apply their respective downstream releases once they incorporate the equivalent Glic fix. Where patching is delayed, compensating controls include enforcing Site Isolation (already on by default) to limit cross-origin impact, blocking access to untrusted sites via enterprise policy or web proxy categorization, and disabling or restricting the Glic feature through enterprise policy if exposed in the deployed channel - note that broad URL blocking can disrupt legitimate browsing and Glic restrictions may degrade dependent product functionality.
