The offsets are derived from firmware-provided strides,\nso the arithmetic can wrap before the bounds check, and the host wrapper\nsize is not the size of the firmware control interface being mapped.\n\nUse 64-bit arithmetic for the computed offsets and validate against the\nactual firmware control interface structure sizes with subtraction-based\nbounds checks. Also validate that the shared section is large enough for\nthe global control interface before using it.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":205218,"id":"CVE-2026-89825","ts":1789570705784,"field":"cvss","old":null,"new":"7.8"},{"seq":205217,"id":"CVE-2026-89825","ts":1789570705784,"field":"severity","old":"none","new":"high"}]}
