{"id":"CVE-2026-89853","summary":"scsi: qla2xxx: Fix FCE trace use-after-free during firmware dump","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Fix FCE trace use-after-free during firmware dump\n\nqla2x00_free_fce_trace() freed and cleared ha-\u003efce while holding only\nfce_mutex. The firmware-dump consumers qla27xx_fwdt_entry_t264() and\nqla25xx_copy_fce() read ha-\u003efce (NULL check followed by a copy of the\nbuffer) under hardware_lock and never take fce_mutex. A debugfs FCE\ndisable could therefore free the DMA buffer between a dump's NULL check\nand its copy, resulting in a use-after-free.\n\nUnpublish ha-\u003efce under hardware_lock, then release the lock and free\nthe DMA buffer (dma_free_coherent() may sleep). A concurrent dump either\ncompletes its check and copy with the buffer still valid, or observes\nha-\u003efce == NULL and skips it.","modified":"2026-11-13T04:02:37.427652260Z","published":"2026-09-16T10:31:27.008Z","related":["SUSE-SU-2026:24550-1","SUSE-SU-2026:24619-1","SUSE-SU-2026:24643-1","SUSE-SU-2026:24648-1","SUSE-SU-2026:24651-1","SUSE-SU-2026:24662-1","SUSE-SU-2026:5091-1","SUSE-SU-2026:5121-1","openSUSE-SU-2026:11880-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89853.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/41ef7edde27ac87d55ffc703da44e78aa8c2e896"},{"type":"WEB","url":"https://git.kernel.org/stable/c/423487f03e325b8665d20a2a3171fe012b1a4fa9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/53298efcbbb0f0438366d45cb7ed7e6d93dd5531"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6003e79148eca73d7cafb076f5be47e234d543d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7bd308cd893e8cce023d03a40a2f0adccaff0175"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8e7a26931b6111583cfeaf49c068f26524dc3af2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/edc464a4fc96e2720d166e7cc7e7a6827b086760"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ef9b89f6c92274c3670403fd06130ca25f685050"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89853.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89853"},{"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":"3a5a789494875376d1f8063ec5ecc6beafda2ce1"},{"fixed":"423487f03e325b8665d20a2a3171fe012b1a4fa9"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"73d3d3c66f108bc47922490f8500842530139975"},{"fixed":"7bd308cd893e8cce023d03a40a2f0adccaff0175"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"57c029cab0d908942e3ed9ff9fd0361144d01944"},{"fixed":"edc464a4fc96e2720d166e7cc7e7a6827b086760"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"217230bc8796a922d5b15a9a94ec4414b2d2b3e3"},{"fixed":"6003e79148eca73d7cafb076f5be47e234d543d0"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2cf3c3fe9a11aa168e80c966494c58548b9aed5d"},{"fixed":"ef9b89f6c92274c3670403fd06130ca25f685050"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"841df27d619ee1f5ca6473e15227b39d6136562d"},{"fixed":"8e7a26931b6111583cfeaf49c068f26524dc3af2"},{"fixed":"41ef7edde27ac87d55ffc703da44e78aa8c2e896"},{"fixed":"53298efcbbb0f0438366d45cb7ed7e6d93dd5531"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"a89872a61b914378591f16e428dd221c5e2059b2"}]}],"versions":["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","v5.15.220","v5.15.219","v5.15.218","v5.15.217","v5.15.216","v5.15.215","v5.15.214","v5.15.213","v5.15.212","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","v5.15.184","v5.15.183","v5.15.182","v5.15.181","v5.15.180","v5.15.179","v6.1.187","v6.1.186","v6.1.185","v6.1.184","v6.1.183","v6.1.182","v6.1.181","v6.1.180","v6.1.179","v6.1.178","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","v6.1.148","v6.1.147","v6.1.146","v6.1.145","v6.1.144","v6.1.143","v6.1.142","v6.1.141","v6.1.140","v6.1.139","v6.1.138","v6.1.137","v6.1.136","v6.1.135","v6.1.134","v6.1.133","v6.1.132","v6.1.131","v6.1.130","v6.1.129","v6.6.156","v6.6.155","v6.6.154","v6.6.153","v6.6.152","v6.6.151","v6.6.150","v6.6.149","v6.6.148","v6.6.147","v6.6.146","v6.6.145","v6.6.144","v6.6.143","v6.6.142","v6.6.141","v6.6.140","v6.6.139","v6.6.138","v6.6.137","v6.6.136","v6.6.135","v6.6.134","v6.6.133","v6.6.132","v6.6.131","v6.6.130","v6.6.129","v6.6.128","v6.6.127","v6
