However, it does not\ncheck if the tachometer value is zero before performing the division.\n\nIf the hardware reports a tachometer value of 0 (which can happen due to\nan extremely fast pulse, a stuck edge, or a hardware glitch), the\ncalculated tach_div evaluates to 0. The subsequent call to do_div() with\ntach_div as the divisor triggers a divide-by-zero exception, leading to\na kernel panic.\n\nCheck the divisor against zero to fix the problem.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/898ca04b096b9e4640300eab91468c826a1ec92b","https://git.kernel.org/stable/c/a3f98bd397398e2d4a7f98e006b5aaf4d54ebdf3","https://git.kernel.org/stable/c/fb8a5afe6f1f8aa7f19c6dda23d277dd6ae5d9e1","https://git.kernel.org/stable/c/fe87b8dc67f1b2c64e76a66e78468c533d3c44ca"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72394","score":0.00209,"percentile":0.11047,"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).
