{"apiVersion":"1.0","identifier":"CVE-2026-72120","description":"In the Linux kernel, the following vulnerability has been resolved: can: bcm: add missing rcu list annotations and operations sashiko-bot remarked the missing use of list_add_rcu() in bcm_[rx|tx]_setup() to have a proper initialized bcm_op structure when bcm_proc_show() traverses the bcm_op-s under rcu_read_lock(). To cover all initial settings of the bcm_op-s the list_add_rcu() calls are moved to the end of the setup code. While at it, also fix the mirroring removal side: bcm_release() called bcm_remove_op() - which frees the op via call_rcu() - on ops that were still linked in bo->tx_ops/bo->rx_ops, without list_del_rcu() first. Unlink each op with list_del_rcu() before handing it to bcm_remove_op(), matching the existing pattern in bcm_delete_tx_op()/bcm_delete_rx_op().","publishedAt":"2026-08-15T06:21:26","lastModifiedAt":"2026-08-17T06:18:11","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72120","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00169,"riskScore":0.79,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72120","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72120","en":"https://www.redsauce.net/en/cves/CVE-2026-72120","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72120","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72120","de":"https://www.redsauce.net/de/cves/CVE-2026-72120","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72120","el":"https://www.redsauce.net/el/cves/CVE-2026-72120"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72120"}}
