| CVE-2010-0298 | 3 Debian, Linux, Redhat | 4 Debian Linux, Linux Kernel, Enterprise Linux and 1 more | 2025-04-11 | N/A |
| The x86 emulator in KVM 83 does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) in determining the memory access available to CPL3 code, which allows guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region, a related issue to CVE-2010-0306. | ||||
| CVE-2010-2242 | 2 Libvirt, Redhat | 2 Libvirt, Rhel Virtualization | 2025-04-11 | N/A |
| Red Hat libvirt 0.2.0 through 0.8.2 creates iptables rules with improper mappings of privileged source ports, which allows guest OS users to bypass intended access restrictions by leveraging IP address and source-port values, as demonstrated by copying and deleting an NFS directory tree. | ||||
| CVE-2010-4525 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Virtualization | 2025-04-11 | N/A |
| Linux kernel 2.6.33 and 2.6.34.y does not initialize the kvm_vcpu_events->interrupt.pad structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via unspecified vectors. | ||||
| CVE-2010-2239 | 2 Libvirt, Redhat | 2 Libvirt, Rhel Virtualization | 2025-04-11 | N/A |
| Red Hat libvirt, possibly 0.6.0 through 0.8.2, creates new images without setting the user-defined backing-store format, which allows guest OS users to read arbitrary files on the host OS via unspecified vectors. | ||||
| CVE-2012-1601 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Virtualization | 2025-04-11 | N/A |
| The KVM implementation in the Linux kernel before 3.3.6 allows host OS users to cause a denial of service (NULL pointer dereference and host OS crash) by making a KVM_CREATE_IRQCHIP ioctl call after a virtual CPU already exists. | ||||
| CVE-2010-0419 | 2 Kvm Qumranet, Redhat | 3 Kvm, Enterprise Linux, Rhel Virtualization | 2025-04-11 | N/A |
| The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing (SMP), does not properly restrict writing of segment selectors to segment registers, which might allow guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region, and replacing an instruction in between emulator entry and instruction fetch. | ||||
| CVE-2017-2620 | 5 Citrix, Debian, Qemu and 2 more | 12 Xenserver, Debian Linux, Qemu and 9 more | 2024-11-21 | N/A |
| Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. | ||||
| CVE-2017-2615 | 5 Citrix, Debian, Qemu and 2 more | 12 Xenserver, Debian Linux, Qemu and 9 more | 2024-11-21 | N/A |
| Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host. | ||||
