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-2016-9106 | 3 Debian, Opensuse, Qemu | 3 Debian Linux, Leap, Qemu | 2025-04-12 | 6.0 Medium |
Memory leak in the v9fs_write function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (memory consumption) by leveraging failure to free an IO vector. | ||||
CVE-2016-1922 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 5.5 Medium |
QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue. | ||||
CVE-2011-4111 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Enterprise Linux Server Supplementary | 2025-04-12 | N/A |
Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message. | ||||
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.
