| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2014-12-17 | CVE-2014-9322 | Improper Privilege Management vulnerability in multiple products arch/x86/kernel/entry_64.S in the Linux kernel before 3.17.5 does not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to gain privileges by triggering an IRET instruction that leads to access to a GS Base address from the wrong space. | 7.8 |
| 2014-12-12 | CVE-2014-8134 | The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel through 3.18 uses an improper paravirt_enabled setting for KVM guest kernels, which makes it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value. | 3.3 |
| 2014-11-10 | CVE-2014-8559 | Resource Exhaustion vulnerability in multiple products The d_walk function in fs/dcache.c in the Linux kernel through 3.17.2 does not properly maintain the semantics of rename_lock, which allows local users to cause a denial of service (deadlock and system hang) via a crafted application. | 5.5 |
| 2014-11-10 | CVE-2014-8369 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.17.2 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges. | 7.8 |
| 2014-11-10 | CVE-2014-3690 | Resource Exhaustion vulnerability in multiple products arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU. | 5.5 |
| 2014-11-10 | CVE-2014-3647 | arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 does not properly perform RIP changes, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application. | 5.5 |
| 2014-11-10 | CVE-2014-3646 | arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through 3.17.2 does not have an exit handler for the INVVPID instruction, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application. | 5.5 |
| 2014-11-10 | CVE-2014-3611 | Race Condition vulnerability in multiple products Race condition in the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c in the KVM subsystem in the Linux kernel through 3.17.2 allows guest OS users to cause a denial of service (host OS crash) by leveraging incorrect PIT emulation. | 4.7 |
| 2014-11-10 | CVE-2014-3610 | The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c. | 5.5 |
| 2014-10-13 | CVE-2014-8086 | Race Condition vulnerability in multiple products Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag. | 4.7 |
