{"id":"CVE-2026-98424","summary":"wifi: cfg80211: undo netns switch if renaming the wiphy fails","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: undo netns switch if renaming the wiphy fails\n\nOnce all the interfaces have been moved, cfg80211_switch_netns()\nmoves the wiphy itself by setting its network namespace and then\nrenaming it, which makes sysfs move it. The rename can fail (but\nonly on allocation failures), leaving things mixed up and hitting\nthe warning there.\n\nIgnoring it isn't great, undo the move and let the change fail\nin this case. If undo fails then WARN, then things would again\nbe stuck in two different network namespaces.","modified":"2026-10-15T02:47:34.925688076Z","published":"2026-10-14T13:27:51.975Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98424.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/739b7bf3942da4cde8eedb143d01a16ed865d1d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/96bef5667b0c4aecb1b850d2343f69b9d684abb9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a41bd1938a9bfe226d444172a7e20e4bd5097960"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98424.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98424"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"463d018323851a608eef52a9427b0585005c647f"},{"fixed":"96bef5667b0c4aecb1b850d2343f69b9d684abb9"},{"fixed":"739b7bf3942da4cde8eedb143d01a16ed865d1d7"},{"fixed":"a41bd1938a9bfe226d444172a7e20e4bd5097960"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98424.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.32"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98424.json"}}],"schema_version":"1.9.0"}
