CVE-2016-2197 | 1 Qemu | 1 Qemu | 2025-04-12 | 5.5 Medium |
QEMU (aka Quick Emulator) built with an IDE AHCI emulation support is vulnerable to a null pointer dereference flaw. It occurs while unmapping the Frame Information Structure (FIS) and Command List Block (CLB) entries. A privileged user inside guest could use this flaw to crash the QEMU process instance resulting in DoS. | ||||
CVE-2011-3346 | 3 Qemu, Redhat, Xen | 3 Qemu, Enterprise Linux, Xen | 2025-04-12 | N/A |
Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs. | ||||
CVE-2015-4037 | 1 Qemu | 1 Qemu | 2025-04-12 | N/A |
The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program. | ||||
CVE-2016-9105 | 3 Debian, Opensuse, Qemu | 3 Debian Linux, Leap, Qemu | 2025-04-12 | 6.0 Medium |
Memory leak in the v9fs_link function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (memory consumption) via vectors involving a reference to the source fid object. | ||||
CVE-2016-4002 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2025-04-12 | 9.8 Critical |
Buffer overflow in the mipsnet_receive function in hw/net/mipsnet.c in QEMU, when the guest NIC is configured to accept large packets, allows remote attackers to cause a denial of service (memory corruption and QEMU crash) or possibly execute arbitrary code via a packet larger than 1514 bytes. | ||||
CVE-2015-8744 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 5.5 Medium |
QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It occurs when a guest sends a Layer-2 packet smaller than 22 bytes.
