Intel on Tuesday released six new security advisories to inform customers about the availability of firmware and software updates that address a total of 15 vulnerabilities across several products.
Two of the advisories have been assigned a high severity rating.
One of them describes a vulnerability affecting some Intel NUC 9 Extreme laptop kits that can be exploited by an authenticated attacker to escalate privileges.
Another high-severity advisory describes three vulnerabilities affecting Intel Ethernet controller X722 and 800 series Linux drivers.
The remaining advisories cover medium-severity issues, including a privilege escalation bug in NUC Pro Chassis Element AverMedia Capture Card drivers, a DoS vulnerability in Optane Persistent Memory, DoS and privilege escalation flaws in graphics drivers, and several DoS vulnerabilities in 800 series network adapters and controllers.
The U.S. Cybersecurity and Infrastructure Security Agency on Tuesday advised users and administrators to review the patches from Intel and take action as necessary.
