Work that runs after\nucsi_unregister() has been called touches freed state: it dereferences\nthe connector array that ucsi_unregister() freed, or registers and\nunregisters the instance a second time.\n\nDisable both work items with disable_work_sync() before unregistering,\nand unregister only if the instance is still registered.\n\nThis issue was found by an in-house static analysis tool.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/41934f92e7a54d4080ac0b17aacc83224946785c","https://git.kernel.org/stable/c/432b58cd959e594909a581b4974396cdbc9d4ca1","https://git.kernel.org/stable/c/63b269ec537dc0fd26d0bd64872c26860d108c9d","https://git.kernel.org/stable/c/ee8577de01c6b6c7dd1d76b52242c54d37a989f4"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98758","score":0.00168,"percentile":0.06042,"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).
