Description jkelly 2026-08-13 13:44:58 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Improper handling of values for some Intel(R) Processors within Ring 0: Kernel, Hypervisor and Bare Metal OS may allow an escalation of privilege. Authorized adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present with special internal knowledge and require no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (high), integrity (high) and availability (none) impacts.

Reproducers, if any, will remain confidential and never be made public, unless done so by the security team.
