| CVE-2021-3392 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2024-02-04 | 2.1 LOW | 3.2 LOW |
| A use-after-free flaw was found in the MegaRAID emulator of QEMU. This issue occurs while processing SCSI I/O requests in the case of an error mptsas_free_request() that does not dequeue the request object 'req' from a pending requests queue. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. Versions between 2.10.0 and 5.2.0 are potentially affected. | |||||

| In QEMU 4.1.0, an out-of-bounds read flaw was found in the ATI VGA implementation. It occurs in the ati_cursor_define() routine 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-2021-20203 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2024-02-04 | 2.1 LOW | 3.2 LOW |
| An integer overflow issue was found in the vmxnet3 NIC emulator of the QEMU for versions up to v5.2.0. It may occur if a guest was to supply invalid values for rx/tx queue size or other NIC parameters. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario. | |||||
| CVE-2020-17380 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-02-04 | 4.6 MEDIUM | 6.3 MEDIUM |
| A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI device emulation support. It could occur while doing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in hw/sd/sdhci.c. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code with privileges of the QEMU process on the host. | |||||
| CVE-2020-25743 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Openstack Platform | 2024-02-04 | 2.1 LOW | 3.2 LOW |
| hw/ide/pci.c in QEMU before 5.1.1 can trigger a NULL pointer dereference because it lacks a pointer check before an ide_cancel_dma_sync call. | |||||
| CVE-2020-25085 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-02-04 | 4.4 MEDIUM | 5.0 MEDIUM |
| QEMU 5.0.0 has a heap-based Buffer Overflow in flatview_read_continue in exec.c because hw/sd/sdhci.c mishandles a write operation in the SDHC_BLKSIZE case. | |||||
| CVE-2020-27616 | 1 Qemu | 1 Qemu | 2024-02-04 | 4.0 MEDIUM | 6.5 MEDIUM |
| ati_2d_blt in hw/display/ati_2d.c in QEMU 4.2.1 can encounter an outside-limits situation in a calculation. A guest can crash the QEMU process. | |||||
| CVE-2021-3409 | 4 Debian, Fedoraproject, Qemu and 1 more | 4 Debian Linux, Fedora, Qemu and 1 more | 2024-02-04 | 4.6 MEDIUM | 5.7 MEDIUM |
| The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this. | |||||
| CVE-2020-29443 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2024-02-04 | 3.3 LOW | 3.9 LOW |
| ide_atapi_cmd_reply_end in hw/ide/atapi.c in QEMU 5.1.0 allows out-of-bounds read access because a buffer index is not validated. | |||||
| CVE-2020-25723 | 1 Qemu | 1 Qemu | 2024-02-04 | 2.1 LOW | 3.2 LOW |
| A reachable assertion issue was found in the USB EHCI emulation code of QEMU. It could occur while processing USB requests due to missing handling of DMA memory map failure. A malicious privileged user within the guest may abuse this flaw to send bogus USB requests and crash the QEMU process on the host, resulting in a denial of service. | |||||
