{"id":"CVE-2026-89597","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-89597","summary":"fbdev: uvesafb: unregister connector callback on init failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: uvesafb: unregister connector callback on init failure\n\nuvesafb_init() registers the v86d connector callback before registering\nthe platform driver. If platform_driver_register() fails, the function\nreturns the error directly and leaves the connector callback registered.\n\nThe later platform-device failure path already unregisters the callback.\nAdd the same cleanup before the final return when platform-driver\nregistration fails.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code.","published":"2026-09-11T19:44:59.538Z","modified":"2026-09-14T03:46:17.050858170Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.12.109"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/466a8af0dee2cf745307155e26884e19a37b7e15"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9e768ae51426af2034d479133cfd73010d641b1a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9f8a822b44c42502f105cf6574f4867067eecdd0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de8db23aa7c337e606fca9faf48b3ba72968597a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89597.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89597"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-14T03:46:17.050858170Z"}}
