Description

gen_rand_uuid in lib/uuid.c in Das U-Boot v2014.04 through v2019.04 lacks an srand call, which allows attackers to determine UUID values in scenarios where CONFIG_RANDOM_UUID is enabled, and Das U-Boot is relied upon for UUID values of a GUID Partition Table of a boot device.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
