That is wrong, the registration has to\nbe removed always.\n\nTo fix this, remove the registration from the list and free\nit unconditionally, instead of doing it only when the ref reference\ncounter reaches zero.","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":[],"references":["https://git.kernel.org/stable/c/769324eb35143462542cdb15483cdaf4877bf661","https://git.kernel.org/stable/c/b27e32e9367dac024cd6f61f22655714f483fd67","https://git.kernel.org/stable/c/b446631f355ece73b13c311dd712c47381a23172","https://git.kernel.org/stable/c/769324eb35143462542cdb15483cdaf4877bf661","https://git.kernel.org/stable/c/b27e32e9367dac024cd6f61f22655714f483fd67"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-27027","score":0.00264,"percentile":0.18354,"date":"2026-11-01"},"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).
