Frequently Asked Questions

1

Which systems should be prioritized for this update?

Prioritize Ubuntu systems running the listed Oracle, AWS, or GCP Linux kernel image packages. The corrected issues span numerous kernel components, including networking, storage, filesystems, cryptography, and architecture-specific code.

2

Can these issues be exploited remotely?

The advisory states only that an attacker could possibly compromise the system. Because affected components include multiple network-facing subsystems and network filesystem services, exposure depends on which kernel features and services are enabled and reachable; the provided data does not identify exploit paths for individual CVEs.

3

How can I determine whether a system is in scope?

Check whether the system has one of the listed Ubuntu kernel packages installed: linux-image-6.17.0-1018-oracle, linux-image-6.17.0-1018-oracle-64k, linux-image-6.17.0-1019-aws, linux-image-6.17.0-1019-aws-64k, linux-image-6.17.0-1020-gcp, linux-image-6.17.0-1020-gcp-64k, or linux-image-aws.
