## From the sources

Incorrect comparison in the Ext2 parser for the Intel(R) Slim Bootloader within Ring 0: Bare Metal OS may allow a denial of service. System software adversary with a privileged user combined with a low complexity attack may enable data corruption. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
