A negative errno then made\nbtrfs_uring_read_extent() unlock and free while\nbtrfs_uring_read_finished() did the same again.\n\nReturn -EIOCBQUEUED so only the deferred path cleans up.","modified":"2026-10-25T02:47:29.803712265Z","published":"2026-10-23T12:19:31.392Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98963.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/033dda5b321f01661de518a8d5c8607ae8675b14"},{"type":"WEB","url":"https://git.kernel.org/stable/c/80a8dbb30d2b00b9c671b02bd73f700f6d20100f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a449433b0e3d4a3715d0bbee078f8c603f03c9f6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98963.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98963"},{"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":"34310c442e175f286b4c06ab5caa4e0b267ea31c"},{"fixed":"033dda5b321f01661de518a8d5c8607ae8675b14"},{"fixed":"a449433b0e3d4a3715d0bbee078f8c603f03c9f6"},{"fixed":"80a8dbb30d2b00b9c671b02bd73f700f6d20100f"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98963.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.57"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98963.json"}}],"schema_version":"1.9.2"}
