Doing a < comparison\nwould be sufficient, but the firmware should be doing\nit correctly, so check more strictly.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"dcaf9f5ecb6f395152609bdc40660d9b593dca63"},{"fixed":"e519a404a5bbba37693cb10fa61794a5fce4fd9b"},{"fixed":"d0d39bed9e95f27a246be91c5929254ac043ed30"},{"fixed":"05ad5a4d421ce65652fcb24d46b7e273130240d6"},{"fixed":"557ba100d8cf3661ff8d71c0b4a2cba8db555ec2"},{"fixed":"c176f03350954b795322de0bfe1d7b514db41f45"},{"fixed":"682b6dc29d98e857e6ca4bbc077c7dc2899b7473"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53589.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.1.0"},{"fixed":"5.4.244"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.181"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.3.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53589.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/05ad5a4d421ce65652fcb24d46b7e273130240d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/557ba100d8cf3661ff8d71c0b4a2cba8db555ec2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/682b6dc29d98e857e6ca4bbc077c7dc2899b7473"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c176f03350954b795322de0bfe1d7b514db41f45"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d0d39bed9e95f27a246be91c5929254ac043ed30"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e519a404a5bbba37693cb10fa61794a5fce4fd9b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53589.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53589"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53589.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
