Fa507Nu
Monthly
Out-of-bounds write in the SmiFlash SMM (System Management Mode) module affects ASUS FA507NU and FA507NV laptop BIOS firmware across all versions. A local administrator can dispatch a crafted Software SMI (SW SMI) request with an oversized length value, causing the SmiFlash handler to write beyond its allocated SMRAM buffer boundary, resulting in a system crash (BSOD) or irreversible BIOS flash corruption. The affected models are designated 'unsupported-when-assigned,' meaning these products were already outside active vendor support when this CVE was issued; no public exploit has been identified at time of analysis.
