{"id":"CVE-2026-64260","summary":"fuse-uring: Avoid queue-\u003estopped races and set/read that value under lock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nfuse-uring: Avoid queue-\u003estopped races and set/read that value under lock\n\nThere are several readers of queue-\u003estopped that check the value\nunder lock, but fuse_uring_commit_fetch() did not and actually\nthe value was not set under the lock in fuse_uring_abort_end_requests()\neither. Especially in fuse_uring_commit_fetch it is important\nto check under a lock, because due to races 'struct fuse_req'\nmight be freed with fuse_request_end, but another thread/cpu\nmight already do teardown work.","modified":"2026-07-28T04:03:02.585066859Z","published":"2026-07-25T08:49:11.395Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64260.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/39c8e925b207afceffaa5382416ed405e0223a03"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4021a3a79eee551d95fe1e1e7c1b195d34ba8c08"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b70a3aca16934c196f92abb17b01c1647b9bb63c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64260.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64260"},{"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":"4a9bfb9b6850fec0685447aed280533cf980de70"},{"fixed":"39c8e925b207afceffaa5382416ed405e0223a03"},{"fixed":"4021a3a79eee551d95fe1e1e7c1b195d34ba8c08"},{"fixed":"b70a3aca16934c196f92abb17b01c1647b9bb63c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64260.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.39"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64260.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
