DescriptionCVE.org

Use after free in Views in Google Chrome on Linux prior to 151.0.7922.72 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Heap corruption in Google Chrome's Views UI framework on Linux affects all versions prior to 151.0.7922.72, where a remote attacker can leverage a use-after-free by luring a victim to a crafted HTML page. Because exploitation requires the user to visit malicious content (UI:R), it is not fully automatable, and there is no public exploit identified at time of analysis; EPSS estimates only a 0.18% exploitation probability (8th percentile) and SSVC records exploitation status as none. Chromium rated the underlying issue Medium severity, though the CVSS base score is 8.8 due to high confidentiality, integrity, and availability impact if successfully exploited.

Technical ContextAI

The flaw resides in Views, Chromium's cross-platform C++ UI toolkit used to render browser chrome and native widgets rather than web page content. The root cause is CWE-416 (Use After Free): an object in the Views subsystem is freed while a dangling reference remains reachable, and subsequent access to that stale pointer corrupts the heap. Attacker-controlled HTML/JS can drive the sequence of UI operations that triggers the premature free and reuse, giving the attacker influence over the contents of the freed-then-reallocated memory. Per the CPE (cpe:2.3:a:google:chrome:*), the affected artifact is the Google Chrome desktop application, with this advisory specifically scoping the Linux build.

RemediationAI

Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on Linux via the Stable channel (relaunch the browser to complete the update), per https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. Because Chrome auto-updates, ensure background updates are not disabled in managed/enterprise fleets and force a policy-driven update where necessary; verify the running version under chrome://settings/help. As an interim compensating control before patching, restrict users from browsing untrusted sites and consider enforcing site isolation and the renderer sandbox (default-on) to raise exploitation cost - note this does not remediate the flaw and only reduces likelihood of a successful chain. Downstream Chromium-based browsers on Linux should be updated to a build incorporating the equivalent Views fix.
