{"id":"UBUNTU-CVE-2022-0175","details":"A flaw was found in the VirGL virtual OpenGL renderer (virglrenderer). The virgl did not properly initialize memory when allocating a host-backed memory resource. A malicious guest could use this flaw to mmap from the guest kernel and read this uninitialized memory from the host, possibly leading to information disclosure.","modified":"2026-04-22T15:14:42.244880Z","published":"2022-02-01T00:00:00Z","related":["USN-5309-1"],"upstream":["CVE-2022-0175"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-0175"},{"type":"REPORT","url":"https://gitlab.freedesktop.org/virgl/virglrenderer/-/merge_requests/654"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5309-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-0175"}],"affected":[{"package":{"name":"virglrenderer","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/virglrenderer@0.6.0-2?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.0-1","0.6.0-2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.6.0-2","binary_name":"libvirglrenderer0"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-0175.json"}},{"package":{"name":"virglrenderer","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/virglrenderer@0.8.2-1ubuntu1.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.8.2-1ubuntu1.1"}]}],"versions":["0.7.0-2","0.8.0-2","0.8.1-6","0.8.2-1","0.8.2-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.8.2-1ubuntu1.1","binary_name":"libvirglrenderer1"},{"binary_version":"0.8.2-1ubuntu1.1","binary_name":"virgl-server"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-0175.json"}},{"package":{"name":"virglrenderer","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/virglrenderer@0.9.1-1~exp1ubuntu2?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.1-1~exp1ubuntu2"}]}],"versions":["0.8.2-5build1","0.8.2-5ubuntu1","0.9.1-1~exp1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.9.1-1~exp1ubuntu2","binary_name":"libvirglrenderer1"},{"binary_version":"0.9.1-1~exp1ubuntu2","binary_name":"virgl-server"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-0175.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
