{"id":"CVE-2024-27067","summary":"xen/evtchn: avoid WARN() when unbinding an event channel","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nxen/evtchn: avoid WARN() when unbinding an event channel\n\nWhen unbinding a user event channel, the related handler might be\ncalled a last time in case the kernel was built with\nCONFIG_DEBUG_SHIRQ. This might cause a WARN() in the handler.\n\nAvoid that by adding an \"unbinding\" flag to struct user_event which\nwill short circuit the handler.","modified":"2026-05-18T05:58:49.145921997Z","published":"2024-05-01T13:04:16.051Z","related":["SUSE-SU-2024:2135-1","SUSE-SU-2024:2203-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20249-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/27xxx/CVE-2024-27067.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/35485dad6e28f9b17884764d4692b1655cb848d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/51c23bd691c0f1fb95b29731c356c6fd69925d17"},{"type":"WEB","url":"https://git.kernel.org/stable/c/99e425032c6ec13584d3cd33846e0c7307501b47"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9e2d4b58c1da48a32905802aaeadba7084b46895"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/27xxx/CVE-2024-27067.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-27067"},{"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":"3c8f5965a99397368d3762a9814a21a3e442e1a4"},{"fixed":"99e425032c6ec13584d3cd33846e0c7307501b47"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"9e90e58c11b74c2bddac4b2702cf79d36b981278"},{"fixed":"35485dad6e28f9b17884764d4692b1655cb848d0"},{"fixed":"9e2d4b58c1da48a32905802aaeadba7084b46895"},{"fixed":"51c23bd691c0f1fb95b29731c356c6fd69925d17"}]}],"versions":["v6.6.22","v6.6.21","v6.6.20","v6.6.19"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-27067.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.23"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.7.11"},{"fixed":"6.8.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-27067.json"}}],"schema_version":"1.7.5"}
