Software description linux – Linux kernel linux-raspi2 – Linux kernel for Raspberry Pi 2 Details It was discovered that the generic SCSI block layer in the Linux kernel didnot properly restrict write operations in certain situations. A localattacker could use this to cause a denial of service (system crash) orpossibly gain administrative privileges. (CVE-2016-10088) Jim Mattson discovered that the KVM implementation in the Linux kernelmismanages the #BP and #OF exceptions. A local attacker in a guest virtualmachine could use this to cause a denial of service (guest OS crash).(CVE-2016-9588) Andrey Konovalov discovered a use-after-free vulnerability in the DCCPimplementation in the Linux kernel.

reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.<\/p>\nReferences<\/h3>\n
