Severity: Medium
Description of Problem
AMD has disclosed several security issues affecting AMD CPUs. These CPU hardware issues may allow code in a guest VM to infer some active memory content of another VM that is running on the same host. Although these are not vulnerabilities in the XenServer product itself, for the convenience of customers we are providing updates that contain updated AMD microcode and corresponding product code changes to mitigate these CPU hardware issues.
These issues have the following identifiers:
- CVE-2024-36350
- CVE-2024-36357
Affected Versions
These issues affect XenServer 8.4.
(Note that Citrix Hypervisor 8.2 CU1 is now End of Life (EoL) and so no longer receives security updates or security bulletins.)
