It's a\nstale sysfs entry that should have been removed but remains with NULL\nops.  The commit changed the error handling to skip the entries after\na NULL con->wq, and this leaves the power device unreleased.\n\nFor addressing the regression, the straight revert is applied here.\nFurther code improvements can be done from the scratch again.","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":["CWE-476"],"references":["https://git.kernel.org/stable/c/3d4044c9e6d2e3f11f1f8b5e0ee8647d3eb1afad","https://git.kernel.org/stable/c/5f73aa2cf8bef4a39baa1591c3144ede4788826e"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:03:23.287444849+00:00"},"epss":{"cve":"CVE-2022-49944","score":0.0022,"percentile":0.1259,"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).
