Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.9
Description:
The issue is related to the implementation of the SEV-SNP and SEV-ES mechanisms in the Linux kernel. An untrusted hypervisor can inject virtual interrupt 29 (#VC) at any point in time and trigger its handler, potentially affecting the confidentiality and integrity of protected information. This can be done by injecting a virtual interrupt, which can have an impact on the system's security.
Recommendations:
For Linux kernel versions prior to 6.9, consider disabling the virtual interrupt 29 (#VC) handler as a temporary workaround until a patch is available. Restrict access to the SEV-SNP and SEV-ES mechanisms to minimize the risk of exploitation. Update to a version of the Linux kernel that is 6.9 or later to fully resolve the issue.
