Go to dashboardVMware ESXi, Workstation, and Fusion have an out-of-bounds read in the HGFS shared-folder component that leaks memory from the vmx process. An attacker who already has administrative rights inside a virtual machine can read that leaked memory, and CISA lists it as actively exploited.

Unknown from the sources.
Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read in HGFS. Successful exploitation allows an attacker with administrative privileges to a virtual machine to leak memory from the vmx process.
CISA required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
