| CVE-2021-4093 | Hig | 0.57 | 8.8 | 0.00 | Feb 18, 2022 | A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example, outs or… | ||
| CVE-2022-1158 | Hig | 0.51 | 7.8 | 0.00 | Aug 5, 2022 | A flaw was found in KVM. When updating a guest's page table entry, vm_pgoff was improperly used as the offset to get the page's pfn. As vaddr and vm_pgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the… | ||
| CVE-2022-3344 | Med | 0.36 | 5.5 | 0.00 | Oct 25, 2022 | A flaw was found in the KVM's AMD nested virtualization (SVM). A malicious L1 guest could purposely fail to intercept the shutdown of a cooperative nested guest (L2), possibly leading to a page fault and kernel panic in the host (L0). | ||
| CVE-2019-3887 | Med | 0.36 | 5.6 | 0.00 | Apr 9, 2019 | A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (MSR) access with nested(=1) virtualization enabled. In that, L1 guest could access L0's APIC register values via L2 guest, when 'virtualize x2APIC mode' is enabled. A guest could use this flaw… | ||
| CVE-2008-2382 | 0.04 | — | 0.07 | Dec 24, 2008 | The protocol_client_msg function in vnc.c in the VNC server in (1) Qemu 0.9.1 and earlier and (2) KVM kvm-79 and earlier allows remote attackers to cause a denial of service (infinite loop) via a certain message. | |||
| CVE-2010-0309 | 0.00 | — | 0.03 | Feb 12, 2010 | The pit_ioport_read function in the Programmable Interval Timer (PIT) emulation in i8254.c in KVM 83 does not properly use the pit_state data structure, which allows guest OS users to cause a denial of service (host OS crash or hang) by attempting to read the /dev/port file. | |||
| CVE-2010-0306 | 0.00 | — | 0.00 | Feb 12, 2010 | The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing (SMP), does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) to restrict instruction execution, which allows guest OS users to cause a denial of service (guest OS crash)… | |||
| CVE-2010-0298 | 0.00 | — | 0.02 | Feb 12, 2010 | 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… | |||
| CVE-2008-4539 | 0.00 | — | 0.01 | Dec 29, 2008 | Heap-based buffer overflow in the Cirrus VGA implementation in (1) KVM before kvm-82 and (2) QEMU on Debian GNU/Linux and Ubuntu might allow local users to gain privileges by using the VNC console for a connection, aka the LGD-54XX "bitblt" heap overflow. NOTE: this issue… |
