The v4l2 control handler is\ninitialized and controls are added, but if v4l2_device_register() or\nvideo_register_device() fails afterward, the handler was never freed,\nleaking memory.\n\nAdd v4l2_ctrl_handler_free() call in the err_v4l2 error path to ensure\nthe control handler is properly freed for all error paths after it is\ninitialized.","modified":"2026-07-08T08:09:35.497072169Z","published":"2026-05-06T11:28:28.268Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43231.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1d8558a232ecb187e8e0328d6347a125f437a0fc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/242b0aabb1866024a7995a767ac330c158b39aa4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/27c508f61963013fdf29097578284099ee7a85a4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2fe28a63d598235595a9601e0d8fdc7c8f4fd575"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7fa9754f48cb8eefa566156be341e63d313247e5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ad85bb5623079a35bd400f51de2e2fbc2170bdb2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b8bf939d77c0cd01118e953bbf554e0fa15e9006"},{"type":"WEB","url":"https://git.kernel.org/stable/c/de204d87e7d61859937272fe30cbdd46a4cfb10a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43231.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43231"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1bf20c3a0c616f44359c573b533d06bae960ee45"},{"fixed":"ad85bb5623079a35bd400f51de2e2fbc2170bdb2"},{"fixed":"242b0aabb1866024a7995a767ac330c158b39aa4"},{"fixed":"2fe28a63d598235595a9601e0d8fdc7c8f4fd575"},{"fixed":"27c508f61963013fdf29097578284099ee7a85a4"},{"fixed":"7fa9754f48cb8eefa566156be341e63d313247e5"},{"fixed":"1d8558a232ecb187e8e0328d6347a125f437a0fc"},{"fixed":"de204d87e7d61859937272fe30cbdd46a4cfb10a"},{"fixed":"b8bf939d77c0cd01118e953bbf554e0fa15e9006"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43231.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.4.0"},{"fixed":"5.10.252"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.202"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.165"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.128"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43231.json"}}],"schema_version":"1.7.5"}
