Otherwise it copies all BATTMGR_STRING_LEN bytes and\nleaves the destination without a terminator.\n\nThose destinations are model_number, serial_number and oem_info, each\nBATTMGR_STRING_LEN and declared next to each other. They go out to user\nspace as val->strval, which power_supply_format_property() prints with\n\"%s\", so a firmware string that fills the whole field makes that read run\ninto the following members.\n\nUse strscpy() so the copy always terminates, the way the SM8350 path\nalready does for the same field.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","score":7.7},"cwes":[],"references":["https://git.kernel.org/stable/c/0e70a9b0d16acf7adebc4f386178a95da27c0027","https://git.kernel.org/stable/c/6cc6c28c9ab6e8ecf901397717a5b391b828cdaf","https://git.kernel.org/stable/c/ab1112df8f4ffa88cb024dd370c432ced80f77d8","https://git.kernel.org/stable/c/c06028db620854b11ad81b04b0a4e1ead930cb76","https://git.kernel.org/stable/c/ee053561e21ce1e1741dd64ca5ddcdb92e40edc1"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89466","score":0.00142,"percentile":0.03443,"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).
