Dell Client BIOS Improper SMM Communication Buffer Verification (DSA-2024-104)

The Dell BIOS on the remote device is missing a security patch and is, therefore, affected by an Improper SMM communication buffer verification vulnerability. A physical high privileged attacker could potentially exploit this vulnerability leading to arbitrary writes to SMRAM. Note that Nessus ha...

CVE-2025-33045 Legacy Serial Redirection SMRAM Vulnerabilities

APTIOV contains vulnerabilities in the BIOS where a privileged user may cause “Write-what-where Condition” and “Exposure of Sensitive Information to an Unauthorized Actor” through local access. The successful exploitation of these vulnerabilities can lead to information disclosure, arbitrary data...

PT-2025-32958

Name of the Vulnerable Software and Affected Versions: Tcg2Smm affected versions not specified Description: Tcg2Smm contains a flaw that allows writing arbitrary memory inside SMRAM and executing arbitrary code at the SMM level. Recommendations: At the moment, there is no information about a newe...

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-2023-52710

Huawei Matebook D16Model: CREM-WXX9, BIOS: v2.26, As the communication buffer size hasn’t been properly validated to be of the expected size, it can partially overlap with the beginning SMRAM.This can be leveraged by a malicious OS attacker to corrupt data structures stored at the beginning of...

CVE-2023-27373

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. Due to insufficient input validation, an attacker can tamper with a runtime-accessible EFI variable to cause a dynamic BAR setting to overlap SMRAM...

CVE-2023-22615

An issue was discovered in IhisiSmm in Insyde InsydeH2O with kernel 5.0 through 5.5. IHISI subfunction execution may corrupt SMRAM. An attacker can pass an address in the RCX save state register that overlaps SMRAM, thereby coercing an IHISI subfunction handler to overwrite private SMRAM...
