Define the\nassociated schib_config and schib fields as dma64_t to enable automatic\ndetection of incorrect assignments. Also add the missing virt_to_dma64()\ntranslation.\n\nWithout this fix, a wrong address will be used by firmware when storing\nextended format channel measurement data on kernels built with\nCONFIG_RANDOMIZE_IDENTITY_BASE=y.","modified":"2026-10-20T02:30:21.062125613Z","published":"2026-10-18T15:15:44.206Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98475.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/748ec2f7f5df9b4fc742546a8bfc8aa5d847353e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f78226eb743b362f52b212d7763801642539d1c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b11f369be31ea11c746833e4d3ad51dcd6b5fa2b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f4d04425e66af2ecee9d1a49ae0484436f3c2fd1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98475.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98475"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"14edd0d73bfef320fd5be11495687ba537aa6341"},{"fixed":"b11f369be31ea11c746833e4d3ad51dcd6b5fa2b"},{"fixed":"748ec2f7f5df9b4fc742546a8bfc8aa5d847353e"},{"fixed":"7f78226eb743b362f52b212d7763801642539d1c"},{"fixed":"f4d04425e66af2ecee9d1a49ae0484436f3c2fd1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98475.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.9.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98475.json"}}],"schema_version":"1.9.0"}
