Amazon Linux AMI: Security patch for kernel (ALAS-2016-669) (multiple CVEs) Vulnerability

  • Severity: 4
  • Published: March 17, 2016

The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows guest local OS users to gain privileges, cause a denial of service (guest OS crash), or obtain sensitive information by leveraging I/O port access.
