A privileged guest attacker could use this issue to cause QEMU to crash, leading to a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3446)</p> <p>It was discovered that QEMU incorrectly handled SDHCI device emulation. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-3447)</p> <p>It was discovered that QEMU incorrectly handled calculating the checksum of a short-sized fragmented packet. A guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 24.04 LTS. (CVE-2024-3567)</p> <p>It was discovered that the QEMU qemu-img utility incorrectly handled certain crafted image files. An attacker could use this issue to cause QEMU to consume resources, leading to a denial of service, or possibly read and write to an existing external file. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-4467)</p> <p>It was discovered that QEMU incorrectly handled the RSS feature on virtio-net devices. A privileged guest attacker could possibly use this issue to cause QEMU to crash, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS.
