Elevation of Privilege in Linux MANA Driver for Microsoft Azure Network Adapter
CVE-2026-45476 is a use-after-free vulnerability in the Linux MANA Driver associated with the Microsoft Azure Network Adapter. The flaw arises from improper handling of memory after it has been freed, creating a condition in which stale references can be accessed. According to the provided advisory context, an attacker with local authorization and control of the host environment can trigger the memory mishandling flaw in the guest driver. This can expose sensitive information from the guest and may be leveraged to obtain elevated privileges within the guest system.
