CVE-2017-17741

Published: 18 December 2017

The KVM implementation in the Linux kernel through 4.14.7 allows attackers to obtain potentially sensitive information from kernel memory, aka a write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c and include/trace/events/kvm.h.

From the Ubuntu security team

Dmitry Vyukov discovered that the KVM implementation in the Linux kernel contained an out-of-bounds read when handling memory-mapped I/O. A local attacker could use this to expose sensitive information.
