Set ctxm->type from the current loop\nvariable instead of depending on resp->type.\n\nAlso update the loop to advance type from next_valid_type in the for\nstatement, which keeps the control flow simpler for non-valid and\nunchanged entries.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6a4d0774f02d61f8c75ffe2e38a8553410fe52e9"},{"fixed":"c8d53b70166d1dc463ef42adb7293e1a770822c7"},{"fixed":"29732b68a6816a815d58e9ab229844c23617e1e0"},{"fixed":"4ee937107d52f9e5c350e4b5e629760e328b3d9f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43034.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.18.22"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43034.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/29732b68a6816a815d58e9ab229844c23617e1e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4ee937107d52f9e5c350e4b5e629760e328b3d9f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c8d53b70166d1dc463ef42adb7293e1a770822c7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43034.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43034"},{"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/2026/43xxx/CVE-2026-43034.json"}}
