**Name of the Vulnerable Software and Affected Versions** Linux kernel versions used in Ubuntu 18.10 **Description** The issue allows privileged local users to bypass intended Secure Boot restrictions and execute untrusted code by loading arbitrary kernel modules. This occurs due to a modified kernel/module.c, in conjunction with certain configuration options, leading to mishandling of the result of signature verification. **Recommendations** For Ubuntu 18.10, consider disabling UEFI Secure Boot or restricting the loading of kernel modules until a patch is available.
