Specifically, both port read\nURBs are now submitted on resume for open ports, but the context pointer\nof the second URB is left set to the core rather than mos7840 port\nstructure.\n\nFix this by implementing dedicated suspend and resume functions for\nmos7840.\n\nTested with Delock 87414 USB 2.0 to 4x serial adapter.\n\n[ johan: analyse crash and rewrite commit message; set busy flag on\n         resume; drop bulk-in check; drop unnecessary usb_kill_urb() ]","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":[],"references":["https://git.kernel.org/stable/c/1094ed500987e67a9d18b0f95e1812f1cc720856","https://git.kernel.org/stable/c/553e67dec846323b5575e78a776cf594c13f98c4","https://git.kernel.org/stable/c/5ae6a64f18211851c8df6b4221381c438b9a7348","https://git.kernel.org/stable/c/932a86a711c722b45ed47ba2103adca34d225b33","https://git.kernel.org/stable/c/b14aa5673e0a8077ff4b74f0bb260735e7d5e6a4"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:53:51.317825789+00:00"},"epss":{"cve":"CVE-2024-42244","score":0.00229,"percentile":0.1381,"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).
