Descriptions

arch/x86/kvm/x86.c in the Linux kernel before 2.6.36.2 does not initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via read operations on the /dev/kvm device.

arch/x86/kvm/x86.c en el kernel de Linux v2.6.36.2 no inicializa ciertos miembros de estructura, lo que permite a usuarios locales obtener información potencialmente sensible del la pila de la pila de memoria del kernel a través de operaciones de lectura en el dispositivo /dev/kvm device.

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update includes backported fixes for security issues. These issues, except for CVE-2011-1182, only affected users of Red Hat Enterprise Linux 6.0 Extended Update Support as they have already been addressed for users of Red Hat Enterprise Linux 6 in the 6.1 update, RHSA-2011:0542. Security fixes: Buffer overflow flaws were found in the Linux kernel's Management Module Support for Message Passing Technology based controllers. A local, unprivileged user could use these flaws to cause a denial of service, an information leak, or escalate their privileges. Various other issues were also addressed.
