CVE-2023-28252Windows — the log file driver, again

A heap overflow in the Windows common log file system driver hands a local attacker the machine's highest account (SYSTEM). It arrived as a zero-day in ransomware hands, and this driver has produced the same class of flaw repeatedly.

YOUR NEXT MOVE

Install the April 2023 Windows update. Ransomware crews reach for this driver by habit, so an endpoint missing it turns any foothold into full control.
