| CVE-2021-3544 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-10-25 | 6.5 Medium |
| Several memory leaks were found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. They exist in contrib/vhost-user-gpu/vhost-user-gpu.c and contrib/vhost-user-gpu/virgl.c due to improper release of memory (i.e., free) after effective lifetime. | ||||
| CVE-2021-3930 | 3 Debian, Qemu, Redhat | 10 Debian Linux, Qemu, Codeready Linux Builder and 7 more | 2022-10-25 | 6.5 Medium |
| An off-by-one error was found in the SCSI device emulation in QEMU. It could occur while processing MODE SELECT commands in mode_sense_page() if the 'page' argument was set to MODE_PAGE_ALLS (0x3f). A malicious guest could use this flaw to potentially crash QEMU, resulting in a denial of service condition. | ||||
| CVE-2020-17380 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-10-14 | 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-2019-13164 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2022-10-06 | 7.8 High |
| qemu-bridge-helper.c in QEMU 3.1 and 4.0.0 does not ensure that a network interface name (obtained from bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass. | ||||
| CVE-2021-20295 | 1 Qemu | 1 Qemu | 2022-10-06 | 6.5 Medium |
| It was discovered that the update for the virt:rhel module in the RHSA-2020:4676 (https://access.redhat.com/errata/RHSA-2020:4676) erratum released as part of Red Hat Enterprise Linux 8.3 failed to include the fix for the qemu-kvm component issue CVE-2020-10756, which was previously corrected in virt:rhel/qemu-kvm via erratum RHSA-2020:4059 (https://access.redhat.com/errata/RHSA-2020:4059). CVE-2021-20295 was assigned to that Red Hat specific security regression. For more details about the original security issue CVE-2020-10756, refer to bug 1835986 or the CVE page: https://access.redhat.com/security/cve/CVE-2020-10756. | ||||
| CVE-2021-3582 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-10-05 | 6.5 Medium |
| A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. The issue occurs while handling a "PVRDMA_CMD_CREATE_MR" command due to improper memory remapping (mremap). This flaw allows a malicious guest to crash the QEMU process on the host. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-3392 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2022-09-30 | 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. | ||||
| CVE-2021-20203 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2022-09-30 | 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-2020-25723 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-09-30 | 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. | ||||
| CVE-2020-28916 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-09-30 | 5.5 Medium |
| hw/net/e1000e_core.c in QEMU 5.0.0 has an infinite loop via an RX descriptor with a NULL buffer address. | ||||
| CVE-2020-29443 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-09-30 | 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-2021-3527 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2022-09-30 | 5.5 Medium |
| A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a single, large transfer request, to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a denial of service. | ||||
| CVE-2021-20263 | 1 Qemu | 1 Qemu | 2022-09-30 | 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-2021-3409 | 4 Debian, Fedoraproject, Qemu and 1 more | 4 Debian Linux, Fedora, Qemu and 1 more | 2022-09-30 | 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-2020-16092 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2022-09-30 | 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-2021-4145 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2022-09-28 | 6.5 Medium |
| A NULL pointer dereference issue was found in the block mirror layer of QEMU in versions prior to 6.2.0. The `self` pointer is dereferenced in mirror_wait_on_conflicts() without ensuring that it's not NULL. A malicious unprivileged user within the guest could use this flaw to crash the QEMU process on the host when writing data reaches the threshold of mirroring node. | ||||
| CVE-2020-25085 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-09-23 | 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-2020-13253 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2022-09-23 | 5.5 Medium |
| sd_wp_addr in hw/sd/sd.c in QEMU 4.2.0 uses an unvalidated address, which leads to an out-of-bounds read during sdhci_write() operations. A guest OS user can crash the QEMU process. | ||||
| CVE-2020-15469 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-09-23 | 2.3 Low |
| In QEMU 4.2.0, a MemoryRegionOps object may lack read/write callback methods, leading to a NULL pointer dereference. | ||||
| CVE-2020-15859 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2022-09-23 | 3.3 Low |
| QEMU 4.2.0 has a use-after-free in hw/net/e1000e_core.c because a guest OS user can trigger an e1000e packet with the data's address set to the e1000e's MMIO address. | ||||
