{"id":"CVE-2026-98967","summary":"cxgb4/ch_ktls: disable softirqs around tid_list erases","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncxgb4/ch_ktls: disable softirqs around tid_list erases\n\nchcr_ktls_cpl_act_open_rpl() inserts into tid_list from the receive path\nusing xa_insert_bh().  The array is shared by the adapter's connections\nand initialized with XA_FLAGS_LOCK_BH.  However, chcr_ktls_dev_del() and\nthe chcr_ktls_dev_add() error path use xa_erase(), which takes the XArray\nlock without disabling softirqs.\n\nWhen cleanup runs with softirqs enabled, a receive softirq for another\nconnection on the same CPU can interrupt the erase and spin on the lock\nheld by the interrupted task.  Use xa_erase_bh() at both sites to match\nthe insertion path.","modified":"2026-11-13T04:07:32.854060196Z","published":"2026-10-23T12:19:37.625Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98967.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0c5063a898813a420e6bad93debd134ef8b3bfd1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2c49ea1dd16d6dc0dd895e6aec57c9a448191cfe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4c9dc0faca98084922caeb689579d338cf3e1c29"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7110c7f70c59eb7924e79853bcc00e2a026662e6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8739f06e3f82cd715f7dd10ab24029ed881efc90"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bafe51bb145e6ae549ae79dcbc35648292625934"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bcf97573d44e277b1744d7f1226f665aa0ccc599"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bea736a2b8c6da5b1078badf1206541b5404250f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98967.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98967"},{"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":"b96adbf6601d76ee0bdd9bfa5bcdd0cdd5333d78"},{"fixed":"2c49ea1dd16d6dc0dd895e6aec57c9a448191cfe"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"65e302a9bd57b62872040d57eea1201562a7cbb2"},{"fixed":"bafe51bb145e6ae549ae79dcbc35648292625934"},{"fixed":"0c5063a898813a420e6bad93debd134ef8b3bfd1"},{"fixed":"8739f06e3f82cd715f7dd10ab24029ed881efc90"},{"fixed":"bcf97573d44e277b1744d7f1226f665aa0ccc599"},{"fixed":"7110c7f70c59eb7924e79853bcc00e2a026662e6"},{"fixed":"bea736a2b8c6da5b1078badf1206541b5404250f"},{"fixed":"4c9dc0faca98084922caeb689579d338cf3e1c29"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"70c4ead897211b184f36cbeda213f2a3e8153218"}]}],"versions":["v5.10.272","v5.10.271","v5.10.270","v5.10.269","v5.10.268","v5.10.267","v5.10.266","v5.10.265","v5.10.264","v5.10.263","v5.10.262","v5.10.261","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","v5.10.237","v5.10.236","v5.10.235","v5.10.234","v5.10.233","v5.10.232","v5.10.231","v5.10.230","v5.10.229","v5.10.228","v5.10.227","v5.10.226","v5.10.225","v5.10.224","v5.10.223","v5.10.222","v5.10.221","v5.10.220","v5.10.219","v5.10.218","v5.10.217","v5.10.216","v5.10.215","v5.10.214","v5.10.213","v5.10.212","v5.10.211","v5.10.210","v5.10.209","v5.10.208","v5.10.207","v5.10.206","v5.10.205","v5.10.204","v5.10.203","v5.10.202","v5.10.201","v5.10.200","v5.10.199","v5.10.198","v5.10.197","v5.10.196","v5.10.195","v5.10.194","v5.10.193","v5.10.192","v5.10.191","v5.10.190","v5.10.189","v5.10.188","v5.10.187","v5.10.186","v5.10.185","v5.10.184","v5.10.183","v5.10.182","v5.10.181","v5.10.180","v5.10.179","v5.10.178","v5.10.177","v5.10.176","v5.10.175","v5.10.174","v5.10.173","v5.10.172","v5.10.171","v5.10.170","v5.10.169","v5.10.168","v5.10.167","v5.10.166","v5.10.165","v5.10.164","v5.10.163","v5.10.162","v5.10.161","v5.10.160","v5.10.159","v5.10.158","v5.10.157","v5.10.156","v5.10.155","v5.10.154","v5.10.153","v5.10.152","v5.10.151","v5.10.150","v5.10.149","v5.10.148","v5.10.147","v5.10.146","v5.10.145","v5.10.144","v5.10.143","v5.10.142","v5.10.141","v5.10.140","v5.10.139","v5.10.138","v5.10.137","v5.10.136","v5.10.135","v5.10.134","v5.10.133","v5.10.132","v5.10.131","v5.10.130","v5.10.129","v5.10.128","v5.10.127","v5.10.126","v5.10.125","v5.10.124","v5.10.123","v5.10.122","v5.10.121","v5.10.120","v5.10.119","v5.10.118","v5.10.117","v5.10.116","v5.10.115","v5.10.114","v5.10.113","v5.10.112","v5.10.111","v5.10.110","v5.10.109","v5.10.108","v5.10.107","v5.10.106","v5.10.105","v5.10.104","v5.10.103","v5.10.102","v5.10.101","v5.10.100","v5.10.99","v5.10.98","v5.10.97","v5.10.96","v5.10.95","v5.10.94","v5.10.93","v5.10.92","v5.10.91","v5.10.90","v5.10.89","v5.10.88","v5.10.87","v5.10.86","v5.10.85","v5.10.84","v5.10.83","v5.10.82","v5.10.81","v5.10.80","v5.10.79","v5.10.78","v5.10.77","v5.10.76","v5.10.75","v5.10.74","v5.10.73","v5.10.72","v5.10.71","v5.10.70","v5.10.69","v5.10.68","v5.10.67","v5.10.66","v5.10.65","v5.10.64","v5.10.63","v5.10.62","v5.10.61","v5.10.60","v5.10.59","v5.10.58","v5.10.57","v5.10.56","v5.10.55","v5.10.54","v5.10.53","v5.10.52","v5.10.51","v5.10.50","v5.10.49","v5.10.48","v5.10.47","v5.10.46","v5.10.45","v5.10.44","v5.10.43","v5.10.42","v5.12.19","v5.12.18","v5.12.17","v5.12.16"
