DATE CVE VULNERABILITY TITLE RISK
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.

2014-11-30 CVE-2014-8989 Permissions, Privileges, and Access Controls vulnerability in Linux Kernel
The Linux kernel through 3.17.4 does not properly restrict dropping of supplemental group memberships in certain namespace scenarios, which allows local users to bypass intended file permissions by leveraging a POSIX ACL containing an entry for the group category that is more restrictive than the entry for the other category, aka a "negative groups" issue, related to kernel/groups.c, kernel/uid16.c, and kernel/user_namespace.c.

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.
4.9
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-2014-3673 Improper Input Validation vulnerability in multiple products
The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (system crash) via a malformed ASCONF chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c.
7.5
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.

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.

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.
