**Name of the Vulnerable Software and Affected Versions** VMware ESXi, Workstation, and Fusion (affected versions not specified) **Description** A use-after-free vulnerability in the XHCI USB controller of VMware products allows a malicious actor with local administrative privileges on a virtual machine to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox, whereas on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** VMware ESXi (affected versions not specified) VMware Workstation (affected versions not specified) VMware Fusion (affected versions not specified) VMware Cloud Foundation (affected versions not specified) **Description** The issue is related to an out-of-bounds write vulnerability. A malicious actor with privileges within the VMX process may trigger an out-of-bounds write, leading to an escape of the sandbox and potentially allowing the attacker to elevate their privileges. **Recommendations** For VMware ESXi, consider restricting access to the VMX process until a patch is available. For VMware Workstation, temporarily disable any functionality that may interact with the VMX process to minimize the risk of exploitation. For VMware Fusion, avoid using any features that may trigger an out-of-bounds write in the VMX process until the issue is resolved. For VMware Cloud Foundation, restrict access to any components that may be affected by the out-of-bounds write vulnerability. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
