CVE-2013-1798

Status Candidate

Overview

The ioapic_read_indirect function in virt/kvm/ioapic.c in the Linux kernel through 3.8.4 does not properly handle a certain combination of invalid IOAPIC_REG_SELECT and IOAPIC_REG_WINDOW operations, which allows guest OS users to obtain sensitive information from host OS memory or cause a denial of service (host OS OOPS) via a crafted application.

Kernel Live Patch Security Notice LSN-0065-1
Posted Apr 15, 2020
Authored by Benjamin M. Romer

Andrew Honig reported a flaw in the way KVM (Kernel-based Virtual Machine) emulated the IOAPIC. A privileged guest user could exploit this flaw to read host memory or cause a denial of service (crash the host). It was discovered that the KVM implementation in the Linux kernel, when paravirtual TLB flushes are enabled in guests, the hypervisor in some situations could miss deferred TLB flushes or otherwise mishandle them. An attacker in a guest VM could use this to expose sensitive information (read memory from another guest VM). Al Viro discovered that the vfs layer in the Linux kernel contained a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory).

Red Hat Security Advisory 2013-1026-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A buffer overflow flaw was found in the way UTF-8 characters were converted to UTF-16 in the utf8s_to_utf16s() function of the Linux kernel's FAT file system implementation. A local user able to mount a FAT file system with the "utf8=1" option could use this flaw to crash the system or, potentially, to escalate their privileges.
