1DescriptionNVD
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. A stack buffer overflow leads to arbitrary code execution in the SetupUtility driver on Intel platforms. An attacker can change the values of certain UEFI variables. If the size of the second variable exceeds the size of the first, then the buffer will be overwritten. This issue affects the SetupUtility driver of InsydeH2O.
AnalysisAI
An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. A stack buffer overflow leads to arbitrary code execution in the SetupUtility driver on Intel platforms. An attacker can change the values of certain UEFI variables. If the size of the second variable exceeds the size of the first, then the buffer will be overwritten. Affected products include: Insyde Kernel. Version information: through 5.5..
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
