QEMU (aka Quick Emulator) built with the USB EHCI emulation support is vulnerable to a null pointer dereference flaw. It could occur when an application attempts to write to EHCI capabilities registers. A privileged user inside quest could use this flaw to crash the QEMU process instance resulting in DoS.

CVE-2013-4539 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Multiple buffer overflows in the tsc210x_load function in hw/input/tsc210x.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a crafted (1) precision, (2) nextprecision, (3) function, or (4) nextfunction value in a savevm image.
CVE-2015-4106 6 Canonical, Citrix, Debian and 3 more 8 Ubuntu Linux, Xenserver, Debian Linux and 5 more 2025-04-12 4.6 MEDIUM N/A
QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors.
CVE-2015-3456 3 Qemu, Redhat, Xen 5 Qemu, Enterprise Linux, Enterprise Virtualization and 2 more 2025-04-12 7.7 HIGH N/A
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.
CVE-2013-4526 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Buffer overflow in hw/ide/ahci.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via vectors related to migrating ports.
CVE-2013-4538 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Multiple buffer overflows in the ssd0323_load function in hw/display/ssd0323.c in QEMU before 1.7.2 allow remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via crafted (1) cmd_len, (2) row, or (3) col values; (4) row_start and row_end values; or (5) col_star and col_end values in a savevm image.
CVE-2016-2858 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2025-04-12 1.9 LOW 6.5 MEDIUM
QEMU, when built with the Pseudo Random Number Generator (PRNG) back-end support, allows local guest OS users to cause a denial of service (process crash) via an entropy request, which triggers arbitrary stack based allocation and memory corruption.
CVE-2016-9104 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2025-04-12 2.1 LOW 4.4 MEDIUM
Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via a crafted offset, which triggers an out-of-bounds access.
CVE-2016-5337 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2025-04-12 2.1 LOW 5.5 MEDIUM
The megasas_ctrl_get_info function in hw/scsi/megasas.c in QEMU allows local guest OS administrators to obtain sensitive host memory information via vectors related to reading device control information.
