Senserva AI Opinion for CVE-2010-0806
Sixteen years after disclosure, CISA placed this Internet Explorer use-after-free on the KEV list in May 2026, meaning attackers still find targets running it. An invalid pointer accessed after object deletion gives remote code execution from a web page. The affected browser generation is end-of-life, so the fix is elimination, not an update.
Do this: Hunt down and retire any system old enough to run the affected Internet Explorer builds.
