Use after free in Network in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Remote code execution in Google Chrome versions prior to 149.0.7827.53 stems from a use-after-free flaw in the Network component, allowing a remote attacker to execute arbitrary code within the renderer process when a user visits a crafted HTML page. Google rated this issue Critical at the Chromium level, and a vendor patch is available; no public exploit identified at time of analysis.
Technical ContextAI
The flaw is classified as CWE-416 (Use After Free) inside Chrome's Network stack, which handles HTTP(S), WebSocket, and other network protocol parsing and lifetime management of request/response objects. Use-after-free conditions in this subsystem typically arise when a network-related object is freed while still referenced by another handler, allowing an attacker to reclaim the freed memory with controlled data and influence subsequent dereferences. Affected products per CPE-equivalent data: Google Chrome desktop builds at versions strictly below 149.0.7827.53 across the Stable channel, with Chromium-derived browsers (Edge, Brave, Opera, Vivaldi) typically inheriting the same defect until they rebase.
RemediationAI
Vendor-released patch: Google Chrome 149.0.7827.53 (Stable channel). Update Chrome on Windows, macOS, and Linux endpoints to 149.0.7827.53 or later via the built-in updater or enterprise management (Chrome Browser Cloud Management, MSI/PKG redeploy) as detailed at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html, and trigger a browser restart to load the new binary. For Chromium-based derivatives (Edge, Brave, Opera, Vivaldi), apply the corresponding vendor build that incorporates the upstream fix tracked at https://issues.chromium.org/issues/503420443. Until patching completes, compensating controls include enforcing Chrome's Site Isolation (already default), enabling Enhanced Safe Browsing to block known malicious pages, restricting browsing to a curated allowlist via group policy (URLBlocklist/URLAllowlist), and isolating high-risk web browsing in a remote browser or VM - note that allowlisting breaks general web usability and Safe Browsing offers no protection against unknown attacker-controlled pages.
