{"id":"CVE-2026-72120","summary":"can: bcm: add missing rcu list annotations and operations","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: bcm: add missing rcu list annotations and operations\n\nsashiko-bot remarked the missing use of list_add_rcu() in\nbcm_[rx|tx]_setup() to have a proper initialized bcm_op structure\nwhen bcm_proc_show() traverses the bcm_op's under rcu_read_lock().\n\nTo cover all initial settings of the bcm_op's the list_add_rcu() calls\nare moved to the end of the setup code.\n\nWhile at it, also fix the mirroring removal side: bcm_release() called\nbcm_remove_op() - which frees the op via call_rcu() - on ops that were\nstill linked in bo-\u003etx_ops/bo-\u003erx_ops, without list_del_rcu() first.\nUnlink each op with list_del_rcu() before handing it to bcm_remove_op(),\nmatching the existing pattern in bcm_delete_tx_op()/bcm_delete_rx_op().","modified":"2026-10-17T10:30:18.063085746Z","published":"2026-08-15T05:52:59.226Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72120.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/30f7bb922cb7e7f072a56c7cb7a5efccd2ceca1d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4e22e8b505f877573bbdfdbcb680babad9b2f7a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7b2c3eabc4dafc062a25e10711154f2107526a78"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8357255e56dc1aaa437e3c53ee9385de984e0d57"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e1c7257c81577130f5ce90f69b2a2c3ce63f957"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b06a4a397ac826603f39875cb7c7819a41365196"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eb1c26eab4d1f0b4450439b4b88c3e73faf1da98"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f53bdab85e64eb57d6899a30d1307fd5a3639cc7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72120.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72120"},{"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":"659701c0b954ccdb4a916a4ad59bbc16e726d42c"},{"fixed":"8357255e56dc1aaa437e3c53ee9385de984e0d57"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0622846db728a5332b917c797c733e202c4620ae"},{"fixed":"8e1c7257c81577130f5ce90f69b2a2c3ce63f957"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6d7d458c41b98a5c1670cbd36f2923c37de51cf5"},{"fixed":"eb1c26eab4d1f0b4450439b4b88c3e73faf1da98"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1f912f8484e9c4396378c39460bbea0af681f319"},{"fixed":"f53bdab85e64eb57d6899a30d1307fd5a3639cc7"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"63567ecd99a24495208dc860d50fb17440043006"},{"fixed":"4e22e8b505f877573bbdfdbcb680babad9b2f7a1"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"dac5e6249159ac255dad9781793dbe5908ac9ddb"},{"fixed":"b06a4a397ac826603f39875cb7c7819a41365196"},{"fixed":"30f7bb922cb7e7f072a56c7cb7a5efccd2ceca1d"},{"fixed":"7b2c3eabc4dafc062a25e10711154f2107526a78"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.10.238"},{"fixed":"5.10.261"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.15.185"},{"fixed":"5.15.212"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.1.141"},{"fixed":"6.1.178"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.6.93"},{"fixed":"6.6.145"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.12.31"},{"fixed":"6.12.97"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.4.294"},{"fixed":"5.5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.14.9"},{"fixed":"6.15"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"19f553a1ddf260da6570ed8f8d91a8c87f49b63a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"7c9db92d5f0eadca30884af75c53d601edc512ee"}]}],"versions":["v5.10.260","v5.10.259","v5.10.258","v5.10.257","v5.10.256","v5.10.255","v5.10.254","v5.10.253","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","v5.15.211","v5.15.210","v5.15.209","v5.15.208","v5.15.207","v5.15.206","v5.15.205","v5.15.204","v5.15.203","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","v6.1.177","v6.1.176","v6.1.175","v6.1.174","v6.1.173","v6.1.172","v6.1.171","v6.1.170","v6.1.169","v6.1.168","v6.1.167","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","v6.1.152","v6.1.151","v6.1.150","v6.1.149","v6.1
