Create wrappers that add locking for\npaths outside of the core interrupt code.\n\nIn particular, irq_type is updated holding igate, therefore testing\nis_intx() requires holding igate.  For example clearing DisINTx from\nconfig space can otherwise race changes of the interrupt configuration.\n\nThis aligns interfaces which may trigger the INTx eventfd into two\ncamps, one side serialized by igate and the other only enabled while\nINTx is configured.  A subsequent patch introduces synchronization for\nthe latter flows.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/03505e3344b0576fd619416793a31eae9c5b73bf","https://git.kernel.org/stable/c/04a4a017b9ffd7b0f427b8c376688d14cb614651","https://git.kernel.org/stable/c/1e71b6449d55179170efc8dee8664510bb813b42","https://git.kernel.org/stable/c/3dd9be6cb55e0f47544e7cdda486413f7134e3b3","https://git.kernel.org/stable/c/3fe0ac10bd117df847c93408a9d428a453cd60e5"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:48:32.179249784+00:00"},"epss":{"cve":"CVE-2024-26810","score":0.00197,"percentile":0.09339,"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).
