{"id":"CVE-2026-89883","summary":"media: rc: sunxi-cir: Unregister rc device on probe failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: rc: sunxi-cir: Unregister rc device on probe failure\n\nAfter rc_register_device() succeeds, later probe failures must undo the\nregistration with rc_unregister_device(). The current error path jumps to\nthe allocation cleanup label and only calls rc_free_device(), leaving the\nrc device registration and resources created by rc_register_device()\nbehind.\n\nAdd a registered-device unwind label for the IRQ lookup, IRQ request, and\nhardware initialization failure paths. Keep rc_free_device() for failures\nbefore rc_register_device() succeeds.","modified":"2026-09-17T03:47:19.782327008Z","published":"2026-09-16T10:31:48.378Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89883.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4655a591478e4b31a3396695a2457daad9d4c899"},{"type":"WEB","url":"https://git.kernel.org/stable/c/479aa6fa8c50f1052f1451326ef7d4d586d340c3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4efd7146dcf959afe64e9c51531cd8f82e60eab6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/59951b8a87ef4fb4b5b9409f70ba07663681a040"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5b58d8c206f37525c8217171e1f3e91dd2fa55e5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5e6f5bffaa80fc8ecce348ec0e34fed9d843e47e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/826763adbd8bd3137c5b3756650da473dc6216d5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89883.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89883"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b4e3e59fb59c214c5bcf9d1bf2971f100e0dac4f"},{"fixed":"4655a591478e4b31a3396695a2457daad9d4c899"},{"fixed":"4efd7146dcf959afe64e9c51531cd8f82e60eab6"},{"fixed":"826763adbd8bd3137c5b3756650da473dc6216d5"},{"fixed":"59951b8a87ef4fb4b5b9409f70ba07663681a040"},{"fixed":"5b58d8c206f37525c8217171e1f3e91dd2fa55e5"},{"fixed":"5e6f5bffaa80fc8ecce348ec0e34fed9d843e47e"},{"fixed":"479aa6fa8c50f1052f1451326ef7d4d586d340c3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89883.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.17.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89883.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
