CVEs 3
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

USN-3084-1 fixed vulnerabilities in the Linux kernel for Ubuntu
16.04 LTS. This update provides the corresponding updates for the
Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for
Ubuntu 14.04 LTS.

Pengfei Wang discovered a race condition in the audit subsystem in the
Linux kernel. A local attacker could use this to corrupt audit logs or
disrupt system-call auditing. (CVE-2016-6136)

It was discovered that the powerpc and powerpc64 hypervisor-mode KVM
implementation in the Linux kernel for did not properly maintain state
about transactional memory. An unprivileged attacker in a guest could cause
a denial of service (CPU lockup) in the host OS. (CVE-2016-5412)

Pengfei Wang discovered a race condition in the Chrome OS embedded
controller device driver in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash). (CVE-2016-6156)
