CVE-2025-7026

A vulnerability in the Software SMI handler SwSmiInputValue 0xB2 allows a local attacker to control the RBX register, which is used as an unchecked pointer in the CommandRcx0 function. If the contents at RBX match certain expected values e.g., '$DB$' or '2DB$', the function performs arbitrary...

CVE-2025-7027

A vulnerability in the Software SMI handler SwSmiInputValue 0xB2 allows a local attacker to control both the read and write addresses used by the CommandRcx1 function. The write target is derived from an unvalidated UEFI NVRAM variable SetupXtuBufferAddress, while the write content is read from a...

CVE-2025-7028

A vulnerability in the Software SMI handler SwSmiInputValue 0x20 allows a local attacker to supply a crafted pointer FuncBlock through RBX and RCX register values. This pointer is passed unchecked into multiple flash management functions ReadFlash, WriteFlash, EraseFlash, and GetFlashInfo that...

CVE-2025-7029

A vulnerability in the Software SMI handler SwSmiInputValue 0xB2 allows a local attacker to control the RBX register, which is used to derive pointers OcHeader, OcData passed into power and thermal configuration logic. These buffers are not validated before performing multiple structured memory...
