The\npcm_urb.packets[] is gone, as it's allocated by usb_alloc_urb(), hence\nit's found in urb.iso_frame_desc[] instead.\n\nThe conversions are rather straightforward; each embedded struct urb\nis changed to a pointer, and its callers are updated accordingly.\nThe resource for those structs are released in the common destructor\nfunctions (usb6fire_comm_free(), etc), which are called at both the\ninit error path and the disconnect.\n\nNo functional changes, only compile-tested.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3ef9093d83ffecb8e5f6c9d5769a52d39df74f7a","https://git.kernel.org/stable/c/52a43c2d57e774489ac3fbbac06ff02f19bd9a52","https://git.kernel.org/stable/c/8b8559aeaba2e51cfee1779b2383b085991f7d81","https://git.kernel.org/stable/c/999f433c09e4668412bd68ca207ae2b4af863862","https://git.kernel.org/stable/c/9fe49dbc023e82dfaee7b245997d820d01742a9a"],"products":[],"source":"nvd","synced_at":"2026-10-26T07:33:01.631659812+00:00"},"epss":{"cve":"CVE-2026-98428","score":0.00215,"percentile":0.11786,"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).
