CVE-2023-38486 is a medium-severity vulnerability rated 6.4/10 on the CVSS scale. A vulnerability in the secure boot implementation on affected Aruba 9200 and 9000 Series Controllers and Gateways allows an attacker to bypass security controls which would normally prohibit unsigned kernel images from executing. An attacker can use this vulnerability to execute arbitrary runtime operating systems, including unverified and unsigned OS images.. EPSS estimates a 0.29% chance of exploitation in the next 30 days.
