CVE-2022-45163 describes an information-disclosure vulnerability present in select NXP devices when configured in Serial Download Protocol (SDP) mode. The affected devices include models from the i.MX RT and i.MX families, such as i.MX RT 1010, i.MX RT 1015, i.MX RT 1020, i.MX RT 1050, i.MX RT 1060, i.MX 6 Family, i.MX 7Dual/Solo, i.MX 7ULP, i.MX 8M Quad, i.MX 8M Mini, and Vybrid. This vulnerability allows for potential memory leaks to physically proximate attackers during cold and warm boot attacks, when the device is in a security-enabled configuration.
The CVSS score for this vulnerability is 5.3, indicating a medium severity level. It is essential for organizations to recognize the potential risks associated with this vulnerability, especially considering the confidentiality impact is rated as high. Given the nature of the vulnerability, attackers may leverage physical proximity to exploit the flaw.
Organizations should prioritize patching immediately, as the configuration settings allowing SDP mode can lead to significant security threats. The recommended mitigation is to disable the SDP mode by programming a one-time programmable eFUSE. For further assistance, customers can contact NXP directly.
As of now, there are no known public exploits confirmed for this vulnerability, but organizations should remain vigilant. The lack of a known exploitation in the wild does not mitigate the need for immediate action to prevent potential data breaches.
In summary, CVE-2022-45163 presents a significant risk to organizations using affected NXP devices configured in SDP mode. Immediate action is required to mitigate this vulnerability effectively.
