Intel discovers 16 new vulnerabilities in motherboard BIOS

Intel has released a new security bulletin, which lists 16 new BIOS vulnerabilities recently discovered that would allow you to escalate privileges and perform DoS attacks on a PC, bypassing the operating system and related security measures. According to Intel, the vulnerabilities that have emerged would affect Core CPUs from the sixth to the eleventh generation, as well as the Xeon range in the W, E and D models.

Ten of these are classified with a high degree of severity, which results in potential unrestricted access to the computer, three others are rated medium severity and only one is rated low.

Intel however notes that vulnerabilities can only be exploited with physical access to the car . The leaks will therefore not represent a serious problem for companies that have secure workstations, unlike personal laptops more prone to physical attacks. The vulnerabilities are based on several bugs found in the BIOS firmware by Intel, these affect control flow management, buffer overflows, problems with pointers, improper validations and more, which would allow system privileges to be scaled. Others include problems with access control features and default permissions, which would make it possible to perform DoS attacks on a local computer.

In fact, most of these run as part of the operating system, which starts after the BIOS runs the Power-On Self-Test (POST). Intel says it is already working on releasing security patches to mitigate the vulnerabilities that have emerged, although there is no official roadmap yet. In the meantime, the company recommends updating the motherboard BIOS to the latest version available.

Below is the list of affected CPUs:
