    Memory corruption in the IE scripting engine, reachable via a crafted web page — classic drive-by RCE in the context of the current user. It's in the CISA KEV catalog (confirmed exploited in the wild). CVSS attack complexity is High and it needs user interaction (visiting a malicious/compromised page), but reliable exploitation has been demonstrated — treat it as real.

    Apply the November 2019 cumulative / IE security update (covers IE 9/10/11). Where IE isn't required, disable it via GPO and remove it from the default launch path — the Chromium-based Edge is not affected. Patch first; disabling IE is defense-in-depth, not a substitute.

    Triage caveat — we marked this false positive / noise for our fleet: IE11 is disabled via GPO and not launchable by users, yet the scanner still flags hosts purely on patch level. The vulnerable path isn't reachable here. Confirm whether IE is actually exposed in your environment before treating the KEV flag as critical — otherwise it's noise on a managed estate.
