If the driver doesn't check the value of pixclock,\nit may cause divide-by-zero error.\n\nIn sisfb_check_var(), var->pixclock is used as a divisor to caculate\ndrate before it is checked against zero. Fix this by checking it\nat the beginning.\n\nThis is similar to CVE-2022-3061 in i740fb which was fixed by\ncommit 15cf0b8.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-369"],"references":["https://git.kernel.org/stable/c/1d11dd3ea5d039c7da089f309f39c4cd363b924b","https://git.kernel.org/stable/c/6db07619d173765bd8622d63809cbfe361f04207","https://git.kernel.org/stable/c/84246c35ca34207114055a87552a1c4289c8fd7e","https://git.kernel.org/stable/c/99f1abc34a6dde248d2219d64aa493c76bbdd9eb","https://git.kernel.org/stable/c/cd36da760bd1f78c63c7078407baf01dd724f313"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:47:51.568503435+00:00"},"epss":{"cve":"CVE-2024-26777","score":0.00254,"percentile":0.16786,"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).
