{"id":"CVE-2026-72067","summary":"cpu: hotplug: Preserve per instance callback errors","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncpu: hotplug: Preserve per instance callback errors\n\ncpuhp_invoke_callback() unwinds earlier callbacks for the same\nhotplug state when one instance fails. The rollback path currently\nreuses ret, so a successful rollback can hide the original error and\nmake the failed transition look successful.\n\nKeep the rollback result separate from the original error.","modified":"2026-08-18T03:56:19.592217552Z","published":"2026-08-15T05:52:20.268Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72067.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/673db10729fb121ea1b16fe57791a0cb9eac1eb5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/77d4fa8a3ea1c3e8b996ac35e59aee9e77389905"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a68257b90d8a9b6d605abc99469ded45ecba63b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/95232281512b15338549171ed9a2acf21f946ffb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9f7dc355f62c011e4afe8286cf71130d4bfb9d80"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef39758637cc5b603fb05b625c45a98aa306e338"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f77117530fc3f5932ffb107182a6dd34006be9b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe9c8d641f6991614d1229a3ffd3e33b879bba9c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72067.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72067"},{"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":"724a86881d03ee5794148e65142e24ed3621be66"},{"fixed":"fe9c8d641f6991614d1229a3ffd3e33b879bba9c"},{"fixed":"ef39758637cc5b603fb05b625c45a98aa306e338"},{"fixed":"95232281512b15338549171ed9a2acf21f946ffb"},{"fixed":"7a68257b90d8a9b6d605abc99469ded45ecba63b"},{"fixed":"77d4fa8a3ea1c3e8b996ac35e59aee9e77389905"},{"fixed":"f77117530fc3f5932ffb107182a6dd34006be9b6"},{"fixed":"9f7dc355f62c011e4afe8286cf71130d4bfb9d80"},{"fixed":"673db10729fb121ea1b16fe57791a0cb9eac1eb5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72067.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.14.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72067.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"}]}
