If the EOP (End of Parameters) bit is set in the same iteration,\nthe inflated size is returned without re-validation against max.\n\nThis can cause create_feature_instance() to call memcpy_fromio() with a\nsize exceeding the ioremap'd region when a malicious FPGA device provides\ncrafted DFHv1 parameter headers.\n\nAdd a bounds check after the size increment to ensure the accumulated\nsize never exceeds the feature boundary.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/012683accbb7d2bcf1264f2a0ecd6aa1dcea4d68","https://git.kernel.org/stable/c/3b622aa447cf26104f96a8be39539367863bc6b6","https://git.kernel.org/stable/c/9e8bc49f91f3f81d957c4f1c1f09fe94e2f88f6a","https://git.kernel.org/stable/c/b2f6220e929b2a43605331d0139e65dc1640c05c","https://git.kernel.org/stable/c/f3df5386e3bb54626c117bd85e0158d45fb4aea9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72158","score":0.00209,"percentile":0.11051,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
