DescriptionCVE.org

Use after free in Chrome for iOS in Google Chrome on iOS prior to 150.0.7871.47 allowed a remote attacker to execute arbitrary code via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Remote code execution in Google Chrome for iOS prior to 150.0.7871.47 stems from a use-after-free (CWE-416) that a remote attacker can trigger when a victim loads a crafted HTML page. Despite Chromium rating the underlying bug 'Low' severity, the NVD CVSS scores it 8.8 (High) because successful exploitation yields full compromise of the browser process. There is no public exploit identified at time of analysis, and EPSS is low at 0.27% (18th percentile), with CISA SSVC recording no observed exploitation.

Technical ContextAI

The flaw is a use-after-free (CWE-416), a memory-corruption class where code references heap memory after it has been freed, letting an attacker groom the heap to reclaim that allocation and gain control over freed-object contents. It affects Google Chrome on iOS specifically; note that Chrome on iOS is built atop Apple's WKWebView/WebKit engine rather than Blink/V8 due to App Store rules, so the affected component differs from desktop Chrome despite the shared 'chrome' CPE (cpe:2.3:a:google:chrome:*). Use-after-free bugs in browser renderer/DOM handling are a recurring root cause of drive-by RCE, and the 'Memory Corruption' and 'RCE' tags reinforce that the vulnerable path is reachable through untrusted web content.

RemediationAI

Vendor-released patch: update Google Chrome for iOS to 150.0.7871.47 or later via the Apple App Store; on managed iOS fleets, push the update through MDM to force compliance. Because Chrome on iOS auto-updates through the App Store, most users receive the fix automatically, but verify the installed build in Chrome settings for high-value devices. There is no vendor-documented configuration workaround; as an interim compensating control, restrict browsing to trusted sites or use MDM web-content filtering to reduce exposure to attacker-controlled HTML pages, accepting the usability trade-off that legitimate sites may be blocked. Consult the Chrome Releases advisory (http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html) for release details.
