A device with several streams gets only its first one\nmapped, so a guest vSID invalidation cannot reach the others' ATC and IOTLB\nentries; a device with none makes master-\u003estreams a ZERO_SIZE_PTR, read out\nof bounds.\n\nReject the mapping with -EOPNOTSUPP if master-\u003enum_streams is not one.","modified":"2026-09-19T03:47:26.191963848Z","published":"2026-09-17T16:09:47.810Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90425.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0b139ec4641c7d4163d8e345c26cc630e24fa43b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9b37afb2d34d99ec4f8db28134181b5a8ec9a4a5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fb292bfc9be936dade7eef7ec5762de1201983d8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90425.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90425"},{"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":"4dc0d12474f9d4833c3dd96b73d61e406d3f5dc7"},{"fixed":"9b37afb2d34d99ec4f8db28134181b5a8ec9a4a5"},{"fixed":"0b139ec4641c7d4163d8e345c26cc630e24fa43b"},{"fixed":"fb292bfc9be936dade7eef7ec5762de1201983d8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90425.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.17.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90425.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
