Descriptions

The vivid_fb_ioctl function in drivers/media/platform/vivid/vivid-osd.c in the Linux kernel through 4.3.3 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory via a crafted application.

La función vivid_fb_ioctl en drivers/media/platform/vivid/vivid-osd.c en el kernel de Linux hasta la versión 4.3.3 no inicializa cierto miembro de estructura, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de una aplicación manipulada.

Jan Beulich discovered that the KVM svm hypervisor implementation in the Linux kernel did not properly catch Debug exceptions on AMD processors. An attacker in a guest virtual machine could use this to cause a denial of service (system crash) in the host OS. It was discovered that the ppp implementation in the Linux kernel did not ensure that certain slot numbers are valid. A local attacker with the privilege to call ioctl() on /dev/ppp could cause a denial of service (system crash). Various other issues were also addressed.
