{"id":"CVE-2026-97410","summary":"netconsole: take target_cleanup_list_lock in drop_netconsole_target()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetconsole: take target_cleanup_list_lock in drop_netconsole_target()\n\ndrop_netconsole_target() unlinks the target while only holding\ntarget_list_lock. However, when the underlying interface has been\nunregistered, netconsole_netdev_event() moves the target from\ntarget_list to target_cleanup_list, and netconsole_process_cleanups_core()\nwalks that list under target_cleanup_list_lock only.\n\nIf a user removes the configfs target at the same time the cleanup\nworker is iterating target_cleanup_list, list_del() can corrupt the list\nbecause the two paths take disjoint locks while operating on the same\nlist node.\n\nAcquire target_cleanup_list_lock around the list_del() so the unlink is\nserialised against netconsole_process_cleanups_core() regardless of\nwhich list the target currently belongs to. The state transition that\ndowngrades STATE_DEACTIVATED to STATE_DISABLED is left intact and is\nperformed under the same combined locking, preserving the existing\nordering with resume_target().","modified":"2026-09-26T03:48:27.088270774Z","published":"2026-09-24T16:03:17.074Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97410.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/84592ee22f7d1583ce33aa733411ff36c7a1c44c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/91aeb87f052367a5a2743cc93777dfb4386f2f14"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe8e6c0a2f28bdab14cdf7eff4dd9755d3793007"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97410.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97410"},{"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":"97714695ef904a4bdba75ca2f339215c0ae2b1fa"},{"fixed":"84592ee22f7d1583ce33aa733411ff36c7a1c44c"},{"fixed":"fe8e6c0a2f28bdab14cdf7eff4dd9755d3793007"},{"fixed":"91aeb87f052367a5a2743cc93777dfb4386f2f14"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97410.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97410.json"}}],"schema_version":"1.9.0"}
