This can bypass the write check\nthat only runs at mmap time.\n\nClear VM_MAYWRITE before vm_insert_page() in the shared DBR/toggle-page\nbranch, matching the existing policy that userspace writes are not\nexpected for these pages.","modified":"2026-09-19T05:33:49Z","published":"2026-09-17T17:17:51Z","upstream":["CVE-2026-92495"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92495"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102434.json"}}],"schema_version":"1.9.0"}
