With those fields left unset, garbage function pointers\nmay be stored and later invoked from typec_partner_link_device() when a USB\ndevice is linked to the port. Uninitialized pd_revision and usb_capability\nsimilarly leak stack data through partner sysfs.\n\nZero-initialize the descriptor so optional callbacks remain NULL and the\nremaining fields are zero.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/5414144e202a32437e3eb436cd3f5f00d79ad86e","https://git.kernel.org/stable/c/75dc6cb377efd2f4428b7f76d3a590a0bbc10399","https://git.kernel.org/stable/c/88c7e458af53ff781a3f1051708395892b325576"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98759","score":0.00206,"percentile":0.10607,"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).
