Google Chrome for Android: Memory corruption in ContextMenu
Summary
A memory corruption flaw in the ContextMenu component of Google Chrome for Android before 156.0.8078.47 may allow a remote attacker to potentially execute arbitrary code inside the browser sandbox. The attacker must lure a user to open a crafted HTML page, and no login is required. Google rates the issue Low, and CISA SSVC lists exploitation as none and the flaw as not automatable.
Affected
- Google Chrome for Android before 156.0.8078.47
Note: the CVE record lists the affected range as '156.0.8078.47 to < 156.0.8078.47', which is inconsistent. The threshold stated in the CVE description is used here.
Fixed in
- Google Chrome for Android 156.0.8078.47 or later (vendor-stated threshold, per the CVE description)
- Unknown: Android-specific release note not verified. Use the current Android build.
Workaround
Unknown. No vendor workaround found. Updating Chrome is the remedy.
Exploitation
- No evidence of exploitation in the wild found. One aggregator lists KEV: No; the CISA KEV catalog was not checked directly.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- No public proof of concept found.
- An EPSS score of 0.00412 is listed on a related Chromium/Edge entry.
Our recommendation
- Update Chrome on all Android devices via Google Play to the latest build, not only 156.0.8078.47.
- Enable automatic updates and enforce a minimum Chrome version through MDM where available.
- Verify the rollout status on managed devices and check for devices with outdated Chrome.
- Verify the NVD record and the Chromium bug before recording this in a formal risk register.
