  - An error in the way that Windows handles objects in memory.

  - Multiple errors in the way that the Windows Kernel API enforces permissions.

  - An error in the Microsoft Server Message Block (SMB) Server when an attacker
    with valid credentials attempts to open a specially crafted file over the SMB
    protocol on the same machine.

  - Multiple errors in the Windows kernel that could allow an attacker to retrieve
    information that could lead to a Kernel Address Space Layout Randomization
    (ASLR) bypass.

  - Multiple errors leading to 'speculative execution side-channel attacks' that
    affect many modern processors and operating systems including Intel, AMD, and ARM.");

  certain security checks and conduct bounds check bypass, branch target injection,
