mbt transport

About this tag
The MBT Transport (netbt.sys) driver is a Windows kernel component that handles NetBIOS over TCP/IP. Recent discussions on WindowsForum.com highlight a high-severity elevation-of-privilege vulnerability in this driver, caused by an untrusted pointer dereference. This flaw allows a local attacker to escalate privileges to SYSTEM, posing a kernel-level risk. The Indian CERT-In has also flagged this vulnerability in a broader advisory covering Microsoft Edge, Windows storage, certificates, and Azure Databricks. Administrators are urged to apply Microsoft's Patch Tuesday updates and implement mitigation measures to protect against remote code execution and privilege escalation attacks targeting the MBT Transport driver.
