CVE-2025-22224VMware ESXi and Workstation — race condition writes out of bounds

VMware ESXi and Workstation check a value and then use it, leaving a window in which an administrator inside a guest can write out of bounds and run code as the process hosting that guest.

YOUR NEXT MOVE

Apply the Broadcom update for this now; it is the first link of a hypervisor escape chain, so patch it together with the kernel write flaw.
