The sysdev pointer is now used when\nassigning the ACPI companions to the xHCI ports and USB\ndevices.\n\nAssigning the ACPI companion here resulted in the\nfwnode->secondary pointer to be replaced also for the parent\ndwc3 device since the primary fwnode (the ACPI companion)\nwas shared. That was unintentional and it created potential\nside effects like resource leaks.","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/7fd069d65da2e20b1caec3b7bcf9dfbe28c04bb2","https://git.kernel.org/stable/c/9c185fde906a48368bd2d2a8c17d4b6fb3d670af","https://git.kernel.org/stable/c/d7f35934f7ab67bfd9adabc84207e59da9c19108"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49306","score":0.00258,"percentile":0.17527,"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).
