Use after free in Blink 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: Medium)
AnalysisAI
Remote code execution in Google Chrome's Blink rendering engine prior to version 149.0.7827.53 allows a remote attacker to execute arbitrary code within the renderer sandbox by luring a user to a crafted HTML page. The flaw is a use-after-free memory corruption issue (CWE-416) tagged for RCE and DoS impact, and no public exploit has been identified at time of analysis. CISA SSVC currently lists exploitation as 'none' despite the high CVSS 8.8 score, indicating significant theoretical impact but no observed in-the-wild activity yet.
Technical ContextAI
Blink is the open-source browser engine used by Chrome and other Chromium-derived browsers to parse HTML/CSS and execute layout, DOM, and rendering logic. CWE-416 (Use After Free) occurs when a program continues to use a pointer to memory after it has been freed, allowing an attacker who can influence subsequent heap allocations to place attacker-controlled data where freed objects previously lived, enabling arbitrary code execution when the dangling pointer is dereferenced. Because Blink processes untrusted web content in the renderer process, a successful UAF exploit yields code execution constrained to Chrome's renderer sandbox (CVSS scope: Unchanged), and a separate sandbox-escape chain would typically be required to fully compromise the host.
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.53 - upgrade Chrome to this version or later via the Stable channel update documented at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html, and force a relaunch so the new binaries take effect (Chrome holds the prior version in memory until restart). For managed fleets, push the update via Group Policy / Chrome Browser Cloud Management and verify version compliance through chrome://version reporting. Until patching is complete, compensating controls include enabling Site Isolation (already default but verify via chrome://flags), enforcing Enhanced Safe Browsing to block known malicious pages (trade-off: sends URL telemetry to Google), and restricting browsing to allowlisted business sites via web proxy policy (trade-off: high operational friction); also audit and update Chromium-based applications (Edge, Electron apps) once their respective vendors ship a rebased build.
