{"id":"OESA-2022-1733","summary":"qemu security update","details":"QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.\r\n\r\nSecurity Fix(es):\r\n\r\nA DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or, potentially, executing arbitrary code within the context of the QEMU process on the host.(CVE-2021-3929)","modified":"2025-09-03T06:17:36.356456Z","published":"2022-07-01T11:03:56Z","upstream":["CVE-2021-3929"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2022-1733"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-3929"}],"affected":[{"package":{"name":"qemu","ecosystem":"openEuler:22.03-LTS","purl":"pkg:rpm/openEuler/qemu&distro=openEuler-22.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.0-41.oe2203"}]}],"ecosystem_specific":{"x86_64":["qemu-block-iscsi-6.2.0-41.oe2203.x86_64.rpm","qemu-block-curl-6.2.0-41.oe2203.x86_64.rpm","qemu-system-riscv-6.2.0-41.oe2203.x86_64.rpm","qemu-img-6.2.0-41.oe2203.x86_64.rpm","qemu-system-aarch64-6.2.0-41.oe2203.x86_64.rpm","qemu-block-ssh-6.2.0-41.oe2203.x86_64.rpm","qemu-hw-usb-host-6.2.0-41.oe2203.x86_64.rpm","qemu-guest-agent-6.2.0-41.oe2203.x86_64.rpm","qemu-debuginfo-6.2.0-41.oe2203.x86_64.rpm","qemu-system-arm-6.2.0-41.oe2203.x86_64.rpm","qemu-block-rbd-6.2.0-41.oe2203.x86_64.rpm","qemu-debugsource-6.2.0-41.oe2203.x86_64.rpm","qemu-seabios-6.2.0-41.oe2203.x86_64.rpm","qemu-6.2.0-41.oe2203.x86_64.rpm","qemu-system-x86_64-6.2.0-41.oe2203.x86_64.rpm"],"aarch64":["qemu-system-x86_64-6.2.0-41.oe2203.aarch64.rpm","qemu-block-ssh-6.2.0-41.oe2203.aarch64.rpm","qemu-6.2.0-41.oe2203.aarch64.rpm","qemu-system-aarch64-6.2.0-41.oe2203.aarch64.rpm","qemu-debuginfo-6.2.0-41.oe2203.aarch64.rpm","qemu-debugsource-6.2.0-41.oe2203.aarch64.rpm","qemu-system-arm-6.2.0-41.oe2203.aarch64.rpm","qemu-hw-usb-host-6.2.0-41.oe2203.aarch64.rpm","qemu-img-6.2.0-41.oe2203.aarch64.rpm","qemu-block-iscsi-6.2.0-41.oe2203.aarch64.rpm","qemu-system-riscv-6.2.0-41.oe2203.aarch64.rpm","qemu-block-curl-6.2.0-41.oe2203.aarch64.rpm","qemu-block-rbd-6.2.0-41.oe2203.aarch64.rpm","qemu-guest-agent-6.2.0-41.oe2203.aarch64.rpm"],"noarch":["qemu-help-6.2.0-41.oe2203.noarch.rpm"],"src":["qemu-6.2.0-41.oe2203.src.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2022-1733.json"}}],"schema_version":"1.7.3"}
