Dell only fixed the driver security flaw in 2009


Dell has released a patch that fixes several vulnerabilities in its DBUtil BIOS driver after a security researcher discovered that an attacker could have misused that driver to obtain increased system privileges.

The vulnerable driver was first discovered by a safety investigation by Kasif Dekel from SentinelLabs and the team reported their findings to the PC giant as early as December last year. According to a U.S. cybersecurity company, the driver has been vulnerable since 2009, although there is currently no evidence that its shortcomings have been exploited in the wild.
