{"id":"CVE-2026-74606","summary":"eventfs: Fix use-after-free in eventfs_remove_rec()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\neventfs: Fix use-after-free in eventfs_remove_rec()\n\neventfs_remove_rec() recursively removes the child at the current loop\nposition. After the recursive call returns, list_for_each_entry() advances\nby reading list.next from the removed child.\n\nIf free_ei() drops the final reference, release_ei() reuses the list/rcu\nunion to queue an SRCU callback. The child may be freed before that read.\nThe eventfs_mutex serializes list updates, but it does not keep the removed\nchild alive or prevent the SRCU callback from running.\n\nUse list_for_each_entry_safe() to save the next sibling before recursively\nremoving the current child.","modified":"2026-10-28T02:30:40.728015016Z","published":"2026-08-22T15:31:53.819Z","related":["SUSE-SU-2026:24179-1","SUSE-SU-2026:24184-1","SUSE-SU-2026:24197-1","SUSE-SU-2026:24235-1","openSUSE-SU-2026:22091-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74606.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5635211b44969f4816e29ec4d5f8665fb39535d0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/74bb1eaf72d185a78c879eb2678ea500f82f46a8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b77581b25e213e83b79ce11eb30024e55ceeb3e9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f161d7861a0bfdf10af6b738b3b57636204661fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fd73b691702170d37d66f4b0278530cea8ed419a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74606.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74606"},{"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":"5dfb04100326f70e3b2d2872c2476ed20b804837"},{"fixed":"b77581b25e213e83b79ce11eb30024e55ceeb3e9"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"43aa6f97c2d03a52c1ddb86768575fc84344bdbb"},{"fixed":"f161d7861a0bfdf10af6b738b3b57636204661fb"},{"fixed":"5635211b44969f4816e29ec4d5f8665fb39535d0"},{"fixed":"74bb1eaf72d185a78c879eb2678ea500f82f46a8"},{"fixed":"fd73b691702170d37d66f4b0278530cea8ed419a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.6.18"},{"fixed":"6.6.152"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.7.6"},{"fixed":"6.8"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5a43badefe0eccca0c26144c0a44b8d417ce8103"}]}],"versions":["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","v6.6.126","v6.6.125","v6.6.124","v6.6.123","v6.6.122","v6.6.121","v6.6.120","v6.6.119","v6.6.118","v6.6.117","v6.6.116","v6.6.115","v6.6.114","v6.6.113","v6.6.112","v6.6.111","v6.6.110","v6.6.109","v6.6.108","v6.6.107","v6.6.106","v6.6.105","v6.6.104","v6.6.103","v6.6.102","v6.6.101","v6.6.100","v6.6.99","v6.6.98","v6.6.97","v6.6.96","v6.6.95","v6.6.94","v6.6.93","v6.6.92","v6.6.91","v6.6.90","v6.6.89","v6.6.88","v6.6.87","v6.6.86","v6.6.85","v6.6.84","v6.6.83","v6.6.82","v6.6.81","v6.6.80","v6.6.79","v6.6.78","v6.6.77","v6.6.76","v6.6.75","v6.6.74","v6.6.73","v6.6.72","v6.6.71","v6.6.70","v6.6.69","v6.6.68","v6.6.67","v6.6.66","v6.6.65","v6.6.64","v6.6.63","v6.6.62","v6.6.61","v6.6.60","v6.6.59","v6.6.58","v6.6.57","v6.6.56","v6.6.55","v6.6.54","v6.6.53","v6.6.52","v6.6.51","v6.6.50","v6.6.49","v6.6.48","v6.6.47","v6.6.46","v6.6.45","v6.6.44","v6.6.43","v6.6.42","v6.6.41","v6.6.40","v6.6.39","v6.6.38","v6.6.37","v6.6.36","v6.6.35","v6.6.34","v6.6.33","v6.6.32","v6.6.31","v6.6.30","v6.6.29","v6.6.28","v6.6.27","v6.6.26","v6.6.25","v6.6.24","v6.6.23","v6.6.22","v6.6.21","v6.6.20","v6.6.19","v6.6.18","v6.7.12","v6.7.11","v6.7.10","v6.7.9","v6.7.8","v6.7.7","v6.7.6"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74606.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.152"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.104"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.18.45"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"7.1.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74606.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
