CVE-2025-32709Windows socket driver — memory flaw grants administrator

The ancillary function driver behind Windows sockets mishandles memory, letting a user already on the machine raise themselves to administrator. The vendor entry calls it a null pointer dereference; the catalog calls it a use-after-free.

YOUR NEXT MOVE

Install the Microsoft update for this CVE now; the socket driver loads on every Windows host, so treat this as estate-wide rather than targeted.
