{"id":"ALSA-2022:7967","summary":"Moderate: qemu-kvm security, bug fix, and enhancement update","details":"Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm packages provide the user-space component for running virtual machines that use KVM.\n\nThe following packages have been upgraded to a later upstream version: qemu-kvm (7.0.0). (BZ#2064757)\n\nSecurity Fix(es):\n\n* QEMU: hcd-ehci: DMA reentrancy issue leads to use-after-free (CVE-2021-3750)\n* QEMU: fdc: heap buffer overflow in DMA read data transfers (CVE-2021-3507)\n* QEMU: intel-hda: segmentation fault due to stack overflow (CVE-2021-3611)\n* QEMU: NULL pointer dereference in pci_write() in hw/acpi/pcihp.c (CVE-2021-4158)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\n\nAdditional Changes:\n\nFor detailed information on changes in this release, see the AlmaLinux Release Notes linked from the References section.","modified":"2026-02-04T02:48:58.627394Z","published":"2022-11-15T00:00:00Z","related":["CVE-2021-3507","CVE-2021-3611","CVE-2021-3750","CVE-2021-4158"],"references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2022:7967"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2021-3507"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2021-3611"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2021-3750"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2021-4158"},{"type":"REPORT","url":"https://bugzilla.redhat.com/1951118"},{"type":"REPORT","url":"https://bugzilla.redhat.com/1973784"},{"type":"REPORT","url":"https://bugzilla.redhat.com/1999073"},{"type":"REPORT","url":"https://bugzilla.redhat.com/2035002"},{"type":"ADVISORY","url":"https://errata.almalinux.org/9/ALSA-2022-7967.html"}],"affected":[{"package":{"name":"qemu-guest-agent","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-guest-agent"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-img","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-img"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-audio-pa","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-audio-pa"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-block-curl","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-block-curl"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-block-rbd","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-block-rbd"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-common","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-common"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-core","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-device-display-virtio-gpu","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-device-display-virtio-gpu"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-device-display-virtio-gpu-ccw","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-device-display-virtio-gpu-ccw"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-device-display-virtio-gpu-gl","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-device-display-virtio-gpu-gl"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"package":{"name":"qemu-kvm-device-display-virtio-gpu-pci","ecosystem":"AlmaLinux:9","purl":"pkg:rpm/almalinux/qemu-kvm-device-display-virtio-gpu-pci"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"17:7.0.0-13.el9"}]}],"database_specific":{"source":"https://github.com/AlmaLinux/osv-database/blob/master/advisories/almalinux9/ALSA-2022:7967.json"}},{"pack
