CVE-2025-62627 AMD CVE debrief

An untrusted pointer dereference in the ionic cloud driver for VMWare ESXi could allow an attacker with an unprivileged VM to read kernel memory or co-located guest VM memory, potentially resulting in loss of confidentiality or availability. This vulnerability affects ESXi environments, particularly those using AMD-Pensando DPU products. Defenders should assess exposure and potential impact, focusing on ESXi 8.x and ESXi 9.x hosts. The CVE record and NVD entry provide details, but verification from official sources is necessary for affected versions and remediation steps.
