A local information disclosure issue was found in dracut before 045 when generating initramfs images with world-readable permissions when 'early cpio' is used, such as when including microcode updates. Local attacker can use this to obtain sensitive information from these files, such as encryption keys or credentials.
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
