Cryptographic key prediction via weak pseudorandom generation
Published Jun 6, 2023 · Updated Jan 7, 2025
Weak key generation in Canonical Landscape before 19.10.05 allows remote attackers to compromise cryptographic confidentiality. The cryptographic-key generation path uses a non-cryptographic pseudo-random generator, leaving key values insufficiently unpredictable. No authentication or user interaction is required, but Canonical has not disclosed which keys are affected or what protected data they expose.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
