CVE-2020-26200
Kaspersky UEFI Boot Loader Authentication Bypass (UEFI Bootloader)

A component of Kaspersky custom boot loader allowed loading of untrusted UEFI modules due to insufficient check of their authenticity. This component is incorporated in Kaspersky Rescue Disk (KRD) and was trusted by the Authentication Agent of Full Disk Encryption in Kaspersky Endpoint Security (KES).
