Guest-triggered process crash via out-of-bounds write
Published Feb 27, 2026 · Updated Feb 27, 2026
Out-of-bounds write in VMware Workstation 17.x and 25H2 before 25H2U1 allows guest OS users to crash host Workstation processes. Broadcom has not disclosed the affected component or the operation that writes beyond its intended buffer. Exploitation requires non-administrative access inside a guest VM and user interaction, and the reported consequence is limited to crashing some host processes.
