| CVE-2020-27821 | 1 Qemu | 1 Qemu | 2024-02-04 | 2.1 LOW | 6.0 MEDIUM |
| A flaw was found in the memory management API of QEMU during the initialization of a memory region cache. This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial of service. This flaw affects QEMU versions prior to 5.2.0. | |||||
| CVE-2021-20255 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-02-04 | 2.1 LOW | 5.5 MEDIUM |
| A stack overflow via an infinite recursion vulnerability was found in the eepro100 i8255x device emulator of QEMU. This issue occurs while processing controller commands due to a DMA reentry issue. This flaw allows a guest user or process to consume CPU cycles or crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-20263 | 1 Qemu | 1 Qemu | 2024-02-04 | 2.1 LOW | 3.3 LOW |
| A flaw was found in the virtio-fs shared file system daemon (virtiofsd) of QEMU. The new 'xattrmap' option may cause the 'security.capability' xattr in the guest to not drop on file write, potentially leading to a modified, privileged executable in the guest. In rare circumstances, this flaw could be used by a malicious user to elevate their privileges within the guest. | |||||
| CVE-2020-25742 | 1 Qemu | 1 Qemu | 2024-02-04 | 2.1 LOW | 3.2 LOW |
| pci_change_irq_level in hw/pci/pci.c in QEMU before 5.1.1 has a NULL pointer dereference because pci_get_bus() might not return a valid pointer. | |||||
| CVE-2020-24352 | 1 Qemu | 1 Qemu | 2024-02-04 | 2.1 LOW | 5.5 MEDIUM |
| An issue was discovered in QEMU through 5.1.0. An out-of-bounds memory access was found in the ATI VGA device implementation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati_2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service. | |||||
| CVE-2020-11869 | 1 Qemu | 1 Qemu | 2024-02-04 | 2.1 LOW | 3.3 LOW |
| An integer overflow was found in QEMU 4.0.1 through 4.2.0 in the way it implemented ATI VGA emulation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati-2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service. | |||||
| CVE-2020-16092 | 1 Qemu | 1 Qemu | 2024-02-04 | 2.1 LOW | 3.8 LOW |
| In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in hw/net/net_tx_pkt.c. | |||||
| CVE-2020-12829 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2024-02-04 | 2.1 LOW | 3.8 LOW |
| In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write() callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a denial of service. | |||||
| CVE-2020-14415 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2024-02-04 | 2.1 LOW | 3.3 LOW |

| CVE-2020-13754 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2024-02-04 | 4.6 MEDIUM | 6.7 MEDIUM |
| hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation. | |||||
| CVE-2020-10761 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2024-02-04 | 4.0 MEDIUM | 5.0 MEDIUM |
| An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service. | |||||
| CVE-2020-14364 | 4 Debian, Fedoraproject, Qemu and 1 more | 5 Debian Linux, Fedora, Qemu and 2 more | 2024-02-04 | 4.4 MEDIUM | 5.0 MEDIUM |
| An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. | |||||

| In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation. | |||||
| CVE-2020-10702 | 1 Qemu | 1 Qemu | 2024-02-04 | 2.1 LOW | 5.5 MEDIUM |
| A flaw was found in QEMU in the implementation of the Pointer Authentication (PAuth) support for ARM introduced in version 4.0 and fixed in version 5.0.0. A general failure of the signature generation process caused every PAuth-enforced pointer to be signed with the same signature. A local attacker could obtain the signature of a protected pointer and abuse this flaw to bypass PAuth protection for all programs running on QEMU. | |||||
