{"id":"CVE-2026-98091","summary":"btrfs: detach failed sprout device from transaction update list","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: detach failed sprout device from transaction update list\n\nWhen creating the first metadata chunk for a sprout filesystem,\ncreate_chunk() adds the new device to the transaction dev_update_list\nthrough device-\u003epost_commit_list.\n\nIf the subsequent system chunk creation fails, btrfs_init_new_device()\naborts the transaction and releases the device while post_commit_list is\nstill linked. This triggers a warning in btrfs_free_device() and leaves\nthe transaction list referencing freed memory.\n\nDetach the device while holding chunk_mutex before releasing it.","modified":"2026-09-26T03:48:32.532581186Z","published":"2026-09-25T10:24:24.082Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98091.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0ea6814bc0ff7cff443241bd34db9f0f828f3190"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8b001df2b37ca022f710f3254fbb0bcd6d9e1bed"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c93b3c43df561cd9f592cee20ae058b563f9e5b6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e9e7e37afa85db770e6084360b21a21a8b3a583f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98091.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98091"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"bbbf7243d62d8be73b7ef60721c127b36b2d523e"},{"fixed":"e9e7e37afa85db770e6084360b21a21a8b3a583f"},{"fixed":"8b001df2b37ca022f710f3254fbb0bcd6d9e1bed"},{"fixed":"0ea6814bc0ff7cff443241bd34db9f0f828f3190"},{"fixed":"c93b3c43df561cd9f592cee20ae058b563f9e5b6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98091.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.2.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98091.json"}}],"schema_version":"1.9.0"}
