If the buffer\nends at a page or scatterlist boundary, this can read past the valid image\ndata and fault.\n\nCopy the remaining bytes into a zero-initialized u32 before writing the\nfinal word so only valid bytes are read from the input buffer.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2564ac3d3b8b47cd9692a5bf42d668ed7218b54e","https://git.kernel.org/stable/c/3b8938f5fbcf4a918785f9cb4b108782eb4ea717","https://git.kernel.org/stable/c/447b3c893987a0106a65f04b62ec3271892e9d98","https://git.kernel.org/stable/c/4dc1051939e499c838229af035464a5fc7671198","https://git.kernel.org/stable/c/827ec385458adeeda651de2b6f3537e386b1a8d9"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89730","score":0.00216,"percentile":0.11945,"date":"2026-10-25"},"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).
