| Date | Id | Summary | Products | Score | Patch | Annotated |
|---|---|---|---|---|---|---|
| 2021-06-02 | CVE-2020-35503 | A NULL pointer dereference flaw was found in the megasas-gen2 SCSI host bus adapter emulation of QEMU in versions before and including 6.0. This issue occurs in the megasas_command_cancelled() callback function while dropping a SCSI request. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | Qemu | 6.0 | ||
| 2021-06-02 | CVE-2021-3544 | 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. | Qemu | 6.5 | ||
| 2021-06-02 | CVE-2019-12067 | The ahci_commit_buf function in ide/ahci.c in QEMU allows attackers to cause a denial of service (NULL dereference) when the command header 'ad->cur_cmd' is null. | Debian_linux, Qemu | 6.5 | ||
| 2021-06-02 | CVE-2020-27661 | A divide-by-zero issue was found in dwc2_handle_packet in hw/usb/hcd-dwc2.c in the hcd-dwc2 USB host controller emulation of QEMU. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service. | Qemu | 6.5 | ||
| 2021-06-02 | CVE-2021-3545 | An information disclosure vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. The flaw exists in virgl_cmd_get_capset_info() in contrib/vhost-user-gpu/virgl.c and could occur due to the read of uninitialized memory. A malicious guest could exploit this issue to leak memory from the host. | Qemu | 6.5 | ||
| 2021-06-02 | CVE-2021-3546 | A flaw was found in vhost-user-gpu of QEMU in versions up to and including 6.0. An out-of-bounds write vulnerability can allow a malicious guest to crash the QEMU process on the host resulting in a denial of service or potentially execute arbitrary code on the host with the privileges of the QEMU process. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | Qemu | 8.8 | ||
| 2021-05-28 | CVE-2020-35505 | A NULL pointer dereference flaw was found in the am53c974 SCSI host bus adapter emulation of QEMU in versions before 6.0.0. This issue occurs while handling the 'Information Transfer' command. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability. | Qemu | 4.4 | ||
| 2021-05-28 | CVE-2020-35506 | A use-after-free vulnerability was found in the am53c974 SCSI host bus adapter emulation of QEMU in versions before 6.0.0 during the handling of the 'Information Transfer' command (CMD_TI). This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service or potential code execution with the privileges of the QEMU process. | Qemu | 6.7 | ||
| 2021-05-28 | CVE-2013-4536 | An user able to alter the savevm data (either on the disk or over the wire during migration) could use this flaw to to corrupt QEMU process memory on the (destination) host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. | Qemu | 7.8 | ||
| 2021-05-13 | CVE-2021-20181 | A race condition flaw was found in the 9pfs server implementation of QEMU up to and including 5.2.0. This flaw allows a malicious 9p client to cause a use-after-free error, potentially escalating their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity as well as system availability. | Debian_linux, Qemu | 7.5 |
