CVE-2022-36337 is a high-severity stack buffer overflow vulnerability affecting Insyde InsydeH2O firmware kernels 5.0 through 5.5. This flaw in the MebxConfiguration driver allows an attacker with high privileges to achieve arbitrary code execution by manipulating a UEFI variable, which is then read by the BIOS. With a CVSS score of 8.2, this vulnerability poses a significant risk of complete compromise (confidentiality, integrity, and availability) of the affected system. While no public exploits, Metasploit modules, or Nuclei templates are currently available, and there is minimal community discussion or media coverage, the potential for a sophisticated attacker to leverage this vulnerability remains.
