DATE CVE VULNERABILITY TITLE RISK
2015-06-07 CVE-2015-4001 Numeric Errors vulnerability in Linux Kernel
Integer signedness error in the oz_hcd_get_desc_cnf function in drivers/staging/ozwpan/ozhcd.c in the OZWPAN driver in the Linux kernel through 4.0.5 allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted packet.

2015-05-27 CVE-2015-3332 Resource Management Errors vulnerability in multiple products
A certain backport in the TCP Fast Open implementation for the Linux kernel before 3.18 does not properly maintain a count value, which allow local users to cause a denial of service (system crash) via the Fast Open feature, as demonstrated by visiting the chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through 3.16.x kernel builds, including longterm-maintenance releases and ckt (aka Canonical Kernel Team) builds.

4.9
2015-03-16 CVE-2015-1420 Race Condition vulnerability in multiple products
Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function.
1.9
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.

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.

4.6
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-2014-3687 Resource Exhaustion vulnerability in multiple products
The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that trigger an incorrect uncork within the side-effect interpreter.
