Since this\ncan happen asynchronously from the normal behavior of the\ndriver, the cleanup may happen when holding other locks\nin the calling sequence (notably, the cio subchannel lock).\n\nPush the cleanup of the private->cp resources to a workqueue,\nwhere it can be done out from under that lock sequence and\na future patch can safely manage the locking requirements.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","score":8.2},"cwes":[],"references":["https://git.kernel.org/stable/c/0c11f61a876ed6fcca53d442ed3f33ea8362a0f9","https://git.kernel.org/stable/c/4e3301e2a651d742c05914f6074a25b8e41bce19","https://git.kernel.org/stable/c/56100baa0eb7055b1026dfa73e696e8066ff71fd","https://git.kernel.org/stable/c/af1759d8e6e6da9ba94f30a2f92546f406899aa7","https://git.kernel.org/stable/c/c9b85aa2cf73ea645e55e2c2670e0ddebfe1589b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-80549","score":0.00183,"percentile":0.0784,"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).
