CVE-2026-9805

The vulnerability exists in the SMM IHISI command handler's FMTSWriteUseIntelLib function, which processes FMTS command 0x32 without proper buffer size validation, potentially leading to a buffer overflow. While the severity is rated low, this flaw could be exploited to execute arbitrary code or crash the system. Organizations using affected products should prioritize patching this vulnerability to mitigate potential risks associated with buffer overflow attacks.
