DescriptionCVE.org

Use after free in Views in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Sandbox escape in Google Chrome's Views UI framework (versions prior to 151.0.7922.72) lets a remote attacker who has already compromised the renderer process break out of the sandbox via a crafted HTML page. Google rates the Chromium severity Critical (CVSS 9.6), and while a patch is available on the Stable channel, there is no public exploit identified at time of analysis and EPSS estimates exploitation probability at just 0.31%. Exploitation depends on chaining a prior renderer compromise, so this is one link in a full exploit chain rather than a standalone remote-code-execution bug.

Technical ContextAI

The flaw is a CWE-416 use-after-free in Views, Chromium's cross-platform UI toolkit used to build browser windows, menus, and controls in the privileged browser process. A use-after-free occurs when memory is freed but a dangling pointer to it is later dereferenced; an attacker who controls heap allocations can reclaim the freed region and steer execution or corrupt state. Because Views runs in the higher-privilege browser process (outside the renderer sandbox), a memory-corruption primitive here is a classic sandbox-escape vector. The single CPE (cpe:2.3:a:google:chrome:*) confirms the affected component is the Chrome desktop application itself; the crafted HTML page is the delivery mechanism that drives the renderer to trigger the browser-side free/use sequence.

RemediationAI

Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on the Stable channel, then fully relaunch the browser so the new binary loads (per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html). In managed environments, push the update via your existing browser-management policy and confirm rollout, since Chrome's auto-update can be delayed by pinned versions or offline endpoints. No standalone workaround neutralizes a browser-process UAF, but because exploitation requires a prior renderer compromise, keeping site isolation enabled (default), avoiding untrusted or unnecessary browser extensions, and ensuring the whole Chromium fleet - including embedded/Electron and other Chromium-based browsers - is patched reduces the chance an attacker obtains the renderer foothold this bug depends on; the trade-off of these controls is operational only (extension review overhead), not functional loss of the browser.
