[USN-3084-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 8
CVEs 3
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

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)
