Summary
Andy Lutomirski discovered that the Linux kernel does not properly handle
faults associated with the Stack Segment (SS) register in the x86
architecture. A local attacker could exploit this flaw to gain
administrative privileges. (CVE-2014-9322)
An information leak in the Linux kernel was discovered that could leak the
high 16 bits of the kernel stack address on 32-bit Kernel Virtual Machine
(KVM) paravirt guests. A user in the guest OS could exploit this leak to
obtain information that could potentially be used to aid in attacking the
kernel. (CVE-2014-8134)
Rabin Vincent, Robert Swiecki, Russell King discovered that the ftrace
subsystem of the Linux kernel does not properly handle private syscall
numbers. A local user could exploit this flaw to cause a denial of service
(OOPS). (CVE-2014-7826)
A flaw in the handling of malformed ASCONF chunks by SCTP (Stream Control
Transmission Protocol) implementation in the Linux kernel was discovered. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-3673)
A flaw in the handling of duplicate ASCONF chunks by SCTP (Stream Control
Transmission Protocol) implementation in the Linux kernel was discovered. A
remote attacker could exploit this flaw to cause a denial of service
(panic). (CVE-2014-3687)
It was discovered that excessive queuing by SCTP (Stream Control
Transmission Protocol) implementation in the Linux kernel can cause memory
pressure. A remote attacker could exploit this flaw to cause a denial of
service. (CVE-2014-3688)
Rabin Vincent, Robert Swiecki, Russell Kinglaw discovered a flaw in how the
perf subsystem of the Linux kernel handles private systecall numbers. A
local user could exploit this to cause a denial of service (OOPS) or bypass
ASLR protections via a crafted application. (CVE-2014-7825)
The KVM (kernel virtual machine) subsystem of the Linux kernel
miscalculates the number of memory pages during the handling of a mapping
failure. A guest OS user could exploit this to cause a denial of service
(host OS page unpinning) or possibly have unspecified other impact by
leveraging guest OS privileges. (CVE-2014-8369)
Andy Lutomirski discovered that the Linux kernel does not properly handle
faults associated with the Stack Segment (SS) register on the x86
architecture. A local attacker could exploit this flaw to cause a denial of
service (panic). (CVE-2014-9090)
