CVE-2026-50661

Summary

A BitLocker security feature bypass, scored CVSS 6.1, publicly disclosed but not observed under exploitation, in Microsoft's July 2026 Patch Tuesday release.

Details

The digest recorded it as the third of three zero-days in a record 622-flaw Patch Tuesday, and it is the only one of the three without exploitation evidence attached. That distinction is the analytic point: a publicly disclosed BitLocker bypass matters because it is a defence failing rather than an access route — an attacker already running code on the host, or holding a stolen machine, can avoid the protection that disk encryption is meant to provide. It does not, on the reporting available, provide remote access, so it is a lower operational priority than the two exploited zero-days patched the same day.
