Technical details
A heap-based buffer overflow (CWE-122) exists in the AMD ionic cloud driver for VMware ESXi. The vulnerability is triggered when the driver improperly handles memory allocation on the heap, allowing data to overwrite adjacent memory locations. An attacker with local access and low privileges can exploit this flaw to escalate their permissions to a higher level. Successful exploitation could lead to arbitrary code execution within the context of the ESXi hypervisor. The attack requires local access and carries a high complexity (AC:H) according to the vendor's CVSS assessment.
