The vulnerability is caused by the exposure of the UART debugging interface having a lack of authentication, authorization and access control functionality. Once the interface is soldered and connected to the attacker, they gain root privilege to the system.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"abyssal","depthScore":66,"depthScoreParts":{"impact":53.9,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":233604,"id":"CVE-2026-79589","ts":1793907140914,"field":"exploit_available","old":"false","new":"true"},{"seq":233603,"id":"CVE-2026-79589","ts":1793907140914,"field":"cvss","old":null,"new":"9.8"},{"seq":233602,"id":"CVE-2026-79589","ts":1793907140914,"field":"severity","old":"none","new":"critical"}]}
