| CVE-2022-4172 | 3 Fedoraproject, Qemu, Redhat | 3 Fedora, Qemu, Enterprise Linux | 2025-04-14 | 6.5 Medium |
| An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host. | ||||
| CVE-2022-4144 | 3 Fedoraproject, Qemu, Redhat | 5 Extra Packages For Enterprise Linux, Fedora, Qemu and 2 more | 2025-04-14 | 6.5 Medium |
| An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition. | ||||
| CVE-2015-8701 | 1 Qemu | 1 Qemu | 2025-04-12 | 6.5 Medium |
| QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue. | ||||
| 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-2016-4020 | 4 Canonical, Debian, Qemu and 1 more | 12 Ubuntu Linux, Debian Linux, Qemu and 9 more | 2025-04-12 | 6.5 Medium |
| The patch_instruction function in hw/i386/kvmvapic.c in QEMU does not initialize the imm32 variable, which allows local guest OS administrators to obtain sensitive information from host stack memory by accessing the Task Priority Register (TPR). | ||||
| CVE-2016-2391 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2025-04-12 | 5.0 Medium |
| The ohci_bus_start function in the USB OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors related to multiple eof_timers. | ||||
