Since the lineevent_state::irq was already set, so\nthe subsequent invocation of free_irq() would trigger the above\nwarning call trace. To fix this issue, set the lineevent_state::irq\nafter the IRQ register successfully.","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/657803b918e097e47d99d1489da83a603c36bcdd","https://git.kernel.org/stable/c/69bef19d6b9700e96285f4b4e28691cda3dcd0d1","https://git.kernel.org/stable/c/97da736cd11ae73bdf2f5e21e24446b8349e0168","https://git.kernel.org/stable/c/b1489043d3b9004dd8d5a0357b08b5f0e6691c43","https://git.kernel.org/stable/c/657803b918e097e47d99d1489da83a603c36bcdd"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2022-48660","score":0.00236,"percentile":0.14658,"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).
