{"id":"CVE-2026-43382","summary":"batman-adv: Avoid double-rtnl_lock ELP metric worker","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: Avoid double-rtnl_lock ELP metric worker\n\nbatadv_v_elp_get_throughput() might be called when the RTNL lock is already\nheld. This could be problematic when the work queue item is cancelled via\ncancel_delayed_work_sync() in batadv_v_elp_iface_disable(). In this case,\nan rtnl_lock() would cause a deadlock.\n\nTo avoid this, rtnl_trylock() was used in this function to skip the\nretrieval of the ethtool information in case the RTNL lock was already\nheld.\n\nBut for cfg80211 interfaces, batadv_get_real_netdev() was called - which\nalso uses rtnl_lock(). The approach for __ethtool_get_link_ksettings() must\nalso be used instead and the lockless version __batadv_get_real_netdev()\nhas to be called.","modified":"2026-10-28T02:30:55.447744197Z","published":"2026-05-08T14:21:30.062Z","related":["SUSE-SU-2026:23066-1","SUSE-SU-2026:23068-1","SUSE-SU-2026:23193-1","SUSE-SU-2026:23194-1","SUSE-SU-2026:23221-1","SUSE-SU-2026:23231-1","SUSE-SU-2026:23237-1","SUSE-SU-2026:23241-1","SUSE-SU-2026:23244-1","SUSE-SU-2026:3130-1","SUSE-SU-2026:3166-1","openSUSE-SU-2026:21555-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43382.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/192f40ad8a7dac58dae9199a065dbf7e6e67b75b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2ab9f2531d37775cd79228c1f5d80e6bd08d11d3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4c3ae249431b4fcb315d7dfb4c3a13f9e443fd9b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/77808fe7d03ad0062840b95f431869a8b3d88b24"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b7e5d8ddfdf1d6e9e0808d1adf7736a107372d77"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cfc83a3c71517b59c1047db57da31e26a9dc2f33"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f3ca45673dab0514a887231de6f3243a699d5bfd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fa7b4edfbabdf9235b0ab4bea297fc12b3bec9ca"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43382.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43382"},{"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":"a0019971f340ae02ba54cf1861f72da7e03e6b66"},{"fixed":"4c3ae249431b4fcb315d7dfb4c3a13f9e443fd9b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3c0e0aecb78cb2a2ca1dc701982d08fedb088dc6"},{"fixed":"192f40ad8a7dac58dae9199a065dbf7e6e67b75b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"781a06fd265a8151f7601122d9c2e985663828ff"},{"fixed":"fa7b4edfbabdf9235b0ab4bea297fc12b3bec9ca"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"a7aa2317285806640c844acd4cd2cd768e395264"},{"fixed":"f3ca45673dab0514a887231de6f3243a699d5bfd"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0fdc3c166ac17b26014313fa2b93696354511b24"},{"fixed":"b7e5d8ddfdf1d6e9e0808d1adf7736a107372d77"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"8c8ecc98f5c65947b0070a24bac11e12e47cc65d"},{"fixed":"2ab9f2531d37775cd79228c1f5d80e6bd08d11d3"},{"fixed":"77808fe7d03ad0062840b95f431869a8b3d88b24"},{"fixed":"cfc83a3c71517b59c1047db57da31e26a9dc2f33"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.10.235"},{"fixed":"5.10.253"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.15.179"},{"fixed":"5.15.203"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.1.129"},{"fixed":"6.1.167"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.6.79"},{"fixed":"6.6.130"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.12.16"},{"fixed":"6.12.78"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.4.291"},{"fixed":"5.5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.13.4"},{"fixed":"6.14"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1c334629176c2d644befc31a20d4bf75542f7631"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"af264c2a9adc37f4bdf88ca7f3affa15d8c7de9e"}]}],"versions":["v5.10.252","v5.10.251","v5.10.250","v5.10.249","v5.10.248","v5.10.247","v5.10.246","v5.10.245","v5.10.244","v5.10.243","v5.10.242","v5.10.241","v5.10.240","v5.10.239","v5.10.238","v5.10.237","v5.10.236","v5.10.235","v5.15.202","v5.15.201","v5.15.200","v5.15.199","v5.15.198","v5.15.197","v5.15.196","v5.15.195","v5.15.194","v5.15.193","v5.15.192","v5.15.191","v5.15.190","v5.15.189","v5.15.188","v5.15.187","v5.15.186","v5.15.185","v5.15.184","v5.15.183","v5.15.182","v5.15.181","v5.15.180","v5.15.179","v6.1.166","v6.1.165","v6.1.164","v6.1.163","v6.1.162","v6.1.161","v6.1.160","v6.1.159","v6.1.158","v6.1.157","v6.1.156","v6.1.155","v6.1.154","v6.1.153","v6.1.1
