Check\nthe returned page directly before using it for the IOMMU mapping.","published":"2026-09-17T16:09:23.140Z","modified":"2026-09-19T03:47:26.165441017Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.10.270"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/06dffc96693083dda3412311406e558cf27f1574"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8c486293ddd0af60991408149fc3e964ea888dc4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a4ace31d732b657d774e31fb444c0c27d42c78e5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ac9cd0a669b8be5d178dbd471b0d68039dac58b5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/af95a0ebc0a0db0762be75f51eadf770bad01aaa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d56c3f955b21e5764c1497e295a5b5d0b3a40470"},{"type":"WEB","url":"https://git.kernel.org/stable/c/db46cb9da83a507d86d2bb080bdb09c865da3d0a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fb0b39287ba894dbdfac2901c51788b63f5c2291"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90388.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90388"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-19T03:47:26.165441017Z"}}
