Name of the Vulnerable Software and Affected Versions Toshiba ACPI BIOS version 1.6

Description The issue is related to an error in the BIOS that causes it to only examine the first slot in the Master Boot Record (MBR) table for an active partition. This prevents the system from booting even if the MBR is not malformed. It has been debated whether this issue poses a security risk, as administrative privileges would be required to exploit it, and other denial-of-service (DoS) attacks are possible with such privileges.

Recommendations For Toshiba ACPI BIOS version 1.6, consider updating to a newer version of the BIOS that addresses this issue, if available. As a temporary workaround, ensure that the first slot in the MBR table contains an active partition to allow the system to boot. However, since the provided information does not specify a fixed version, it is essential to check with the manufacturer for updates. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
