CVE-2022-24031 is a high-severity SMM memory corruption vulnerability affecting Insyde InsydeH2O firmware versions 5.1 through 5.5, specifically within the NvmExpressDxe driver. An attacker with high privileges can exploit this by writing predictable data to SMRAM, potentially escalating privileges to SMM. While the CVSS score is 8.2 (HIGH), indicating significant impact (confidentiality, integrity, availability), there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or inclusion in CISA's KEV catalog. Community discussion and media coverage are minimal, suggesting low current attention.
