Technical summary
NVD identifies the weakness as CWE-416 (Use After Free) in V8, Chrome's JavaScript engine. The vulnerability is described as a heap use-after-free that can lead to heap corruption when processing a crafted HTML page. The CVE description says affected Chrome builds were older than 55.0.2883.75 on Mac, Windows, and Linux, and older than 55.0.2883.84 on Android. NVD also lists vulnerable Chrome versions through 54.0.2840.99 in its CPE data.
Defensive priority
Medium. This is a network-reachable browser memory-corruption issue that requires user interaction, so it is not the highest urgency class, but it should still be patched promptly across exposed user fleets.
Recommended defensive actions
- Update Google Chrome to 55.0.2883.75 or later on Mac, Windows, and Linux, and to 55.0.2883.84 or later on Android.
- Verify deployed Chrome versions across managed desktops and mobile devices to ensure no affected builds remain in service.
- Prioritize remediation for users who regularly open untrusted links or HTML content from email, messaging, or the web.
- Treat unexpected browser crashes on affected versions as a signal to accelerate patching and review update compliance.
