{"id":"CVE-2025-68294","summary":"io_uring/net: ensure vectored buffer node import is tied to notification","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring/net: ensure vectored buffer node import is tied to notification\n\nWhen support for vectored registered buffers was added, the import\nitself is using 'req' rather than the notification io_kiocb, sr-\u003enotif.\nFor non-vectored imports, sr-\u003enotif is correctly used. This is important\nas the lifetime of the two may be different. Use the correct io_kiocb\nfor the vectored buffer import.","modified":"2026-04-02T13:03:30.657277Z","published":"2025-12-16T15:06:14.177Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68294.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/14459281e027f23b70885c1cc1032a71c0efd8d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6041803a831266a2a5a5b5af66f7de0845bcbf3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68294.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68294"},{"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":"23371eac7d9a9bca5360cfb3eb3aa08648ee7246"},{"fixed":"14459281e027f23b70885c1cc1032a71c0efd8d7"},{"fixed":"f6041803a831266a2a5a5b5af66f7de0845bcbf3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68294.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.15.0"},{"fixed":"6.17.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68294.json"}}],"schema_version":"1.7.5"}
