The wakeup list node is initialized before registration,\nso it can be deleted without checking whether the device is wakeup-\ncapable like in the original teardown path.\n\n[ rjw: Rename acpi_device_del_list() to acpi_device_cleanup() ]\n[ rjw: Subject and changelog edits ]","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0b9053cd0955c7cd66d71a8442be33926d70e197","https://git.kernel.org/stable/c/15512c6b5dea72fb5f1f41c1aa96f3f32531ca03","https://git.kernel.org/stable/c/83ee65feadc88de681abc6e977d54eceda95abd7","https://git.kernel.org/stable/c/8cc2017aa804f157e717b5fd471e50fbddfec654","https://git.kernel.org/stable/c/a414485ebc2aa50907d0ce97cde2b1a353696897"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90194","score":0.00205,"percentile":0.10437,"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).
