The problem\narises from the following sequence.\n        1. In dwc3_gadget_suspend, there is a chance of a timeout when\n        moving the USB core to the halt state after clearing the\n        run/stop bit by software.\n        2. In dwc3_core_exit, the event buffer is cleared regardless of\n        the USB core's status, which may lead to an SMMU faults and\n        other memory issues. if the USB core tries to access the event\n        buffer address.\n\nTo prevent this hardware quirk on Exynos platforms, this commit ensures\nthat the event buffer address is not cleared by software  when the USB\ncore is active during runtime suspend by checking its status before\nclearing the buffer address.","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/111277b881def3153335acfe0d1f43e6cd83ac93","https://git.kernel.org/stable/c/14e497183df28c006603cc67fd3797a537eef7b9","https://git.kernel.org/stable/c/2189fd13c577d7881f94affc09c950a795064c4b","https://git.kernel.org/stable/c/7bb11a75dd4d3612378b90e2a4aa49bdccea28ab","https://git.kernel.org/stable/c/b72da4d89b97da71e056cc4d1429b2bc426a9c2f"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:54:38.012257375+00:00"},"epss":{"cve":"CVE-2024-46675","score":0.00279,"percentile":0.20349,"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).
