Use after free in DOM in Google Chrome prior to 148.0.7778.216 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 prior to 148.0.7778.216 enables a remote attacker to execute arbitrary code within the renderer sandbox by luring a user to a crafted HTML page that triggers a use-after-free in the DOM implementation. The flaw carries a CVSS 8.8 (High) rating reflecting network reach with required user interaction, and Google has rated the Chromium severity as High; no public exploit is identified at the time of analysis and the issue is not listed in CISA KEV.

Technical ContextAI

The vulnerability is a CWE-416 Use-After-Free in Chromium's Document Object Model (DOM) subsystem, which manages the in-memory tree representing parsed HTML and exposes it to Blink's JavaScript engine. Use-after-free conditions occur when an object's backing memory is freed while a stale pointer remains reachable; subsequent access can be steered toward attacker-controlled memory, typically achieving type confusion or arbitrary read/write primitives leading to code execution within the renderer process. The affected CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* covers the upstream Chrome product, and because Chromium is the foundation for Edge, Brave, Opera, Vivaldi, and Electron-based desktop applications, downstream consumers are likely to be affected pending their own respins.

RemediationAI

Apply the vendor-released patch by upgrading Google Chrome to 148.0.7778.216 or later on all desktop platforms; Chrome's auto-update mechanism will typically deliver this within 24-48 hours, but enterprise environments using managed update controls should explicitly force the relaunch, since the fix is only active after the browser process restarts. Administrators of Chromium-derived browsers should monitor the corresponding vendor channels (Edge Stable, Brave, Opera, Vivaldi) for respins that pull this fix, and Electron application maintainers should rebase to a patched Chromium build. If immediate patching is infeasible, compensating controls include enabling Site Isolation (already default), enforcing Enhanced Safe Browsing, and restricting browsing to allowlisted domains via enterprise policy (URLAllowlist/URLBlocklist) - these reduce exposure to crafted HTML pages but do not block trusted-site compromises or malvertising paths.
