The rollback loop uses the failing\nindex i for every iteration instead of the already registered vector\nindex j.\n\nThat passes the wrong IRQ/dev_id pair to free_irq() and leaves the\nearlier handlers installed. Use j for both pci_irq_vector() and the\nmatching irq_vector entry in the rollback loop.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0205db768570f9a46b20912afa581a0c7a63d8b7","tags":[]},{"url":"https://git.kernel.org/stable/c/2853ce9c88e0e6dd575f95f28b3a8c2b27164115","tags":[]},{"url":"https://git.kernel.org/stable/c/3f92a64545165bdbb36dee8fa35626b295463313","tags":[]},{"url":"https://git.kernel.org/stable/c/a980dec7c69990e4f119bcf6a2ea093d1c4975e8","tags":[]},{"url":"https://git.kernel.org/stable/c/dd817463c9b42a3a9e23d15b86c6c77a6cfb809d","tags":[]},{"url":"https://git.kernel.org/stable/c/e20b16aa3b49f9db5510940740255a987e6f2a6f","tags":[]},{"url":"https://git.kernel.org/stable/c/f39e3ca1f688d7c08954a0794e9bf1e279c83b15","tags":[]},{"url":"https://git.kernel.org/stable/c/fb22a8d2f3ac6665cc8bee197096b6675cac1a9f","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The vulnerability allows for incorrect handling of MSI-X vectors, leading to potential security issues if not properly managed.","exploitability":"Exploitation requires specific conditions, such as a failure in request_irq(), making it moderately difficult.","blast_radius":"If exploited, it could lead to unauthorized access or system instability, depending on the environment.","remediation":"Upgrade to the fixed version 5.19.10 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["kernel","msi-x","vulnerability"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-07T08:45:33.778Z"}}
