{"id":"AZL-35596","summary":"CVE-2023-5088 affecting package qemu for versions less than 6.2.0-21","details":"A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.","modified":"2026-04-01T05:13:01.355620Z","published":"2023-11-03T14:15:08Z","upstream":["CVE-2023-5088"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-5088"}],"affected":[{"package":{"name":"qemu","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/qemu"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.0-21"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-35596.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
