{"id":"CVE-2026-98285","summary":"net: bridge: vlan: fix bugs caused by switchdev deletion errors","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: bridge: vlan: fix bugs caused by switchdev deletion errors\n\nAllowing switchdev to prevent vlan deletion and error out in __vlan_del\ncould cause multiple different issues - inconsistent state, memory leaks\nwhen flushing, NULL pointer dereference on bridge error when flushing.\nIt doesn't make sense to allow it to stop __vlan_del, so log the error\nand continue with software vlan deletion. This is also consistent with\n8021q behaviour.","modified":"2026-10-07T02:47:30.364227881Z","published":"2026-10-06T08:45:46.332Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98285.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/2842ce397dd09882530b42f7fdb0c855767eb24e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ed3ea86db736a30bebf49b947c42730e8451bcd2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98285.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98285"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"bf361ad38165939049a2649b1a0078f3268d4bd1"},{"fixed":"ed3ea86db736a30bebf49b947c42730e8451bcd2"},{"fixed":"2842ce397dd09882530b42f7fdb0c855767eb24e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98285.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.3.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98285.json"}}],"schema_version":"1.9.0"}
