{"id":"AZL-94404","summary":"CVE-2026-64562 affecting package kernel for versions less than 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: nVMX: Hide shadow VMCS right after VMCLEAR\n\nfree_nested() frees the shadow VMCS while vmcs01 still points to it. But\nbecause it is asynchronous with respect to loaded_vmcs_clear(), the vCPU\nmight migrate before the pointer is cleared and __loaded_vmcs_clear()\nmay then execute VMCLEAR.\n\nThe VMCS needs to stay attached until its explicit VMCLEAR completes, but\nthen it can be hidden and the page safely freed.","modified":"2026-08-28T17:47:40.820464246Z","published":"2026-08-04T07:16:31Z","upstream":["CVE-2026-64562"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64562"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-94404.json"}}],"schema_version":"1.9.0"}
