In this case, msc->input stays NULL,\nleading to a crash at a later time.\n\nDetect this condition in the input_configured() hook and reject the device.\n\nThis is not supposed to happen with actual magic mouse devices, but can be\nprovoked by imposing as a magic mouse USB device.","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-476"],"references":["https://git.kernel.org/stable/c/165912d4321c692321c02793068d30700b4e0f1a","https://git.kernel.org/stable/c/17abd396548035fbd6179ee1a431bd75d49676a7","https://git.kernel.org/stable/c/243e1165eb03aca97d87aafa9c3130593837a1c2","https://git.kernel.org/stable/c/36c83c1329dd881f290f7df2feadfb9a21775108","https://git.kernel.org/stable/c/5bbe266272d86c0657e8253600f3d5b74fb7b2ae"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43140","score":0.00128,"percentile":0.02435,"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).
