Descriptions

The xen_failsafe_callback function in Xen for the Linux kernel 2.6.23 and other versions, when running a 32-bit PVOPS guest, allows local users to cause a denial of service (guest crash) by triggering an iret fault, leading to use of an incorrect stack pointer and stack corruption.

La función xen_failsafe_callback de Xen para el kernel de Linux v2.6.23 y otras versiones, mientras ejecuta un invitado PVOPS de 32 bits, permite que usuarios locales provocar una denegación de servicios disparando el retorno de la interrupción (iret), lo que lleva a la utilización de una incorrecto puntero a pila y daños en esta.

It was discovered that hypervkvpd, which is distributed in the Linux kernel, was not correctly validating the origin on Netlink messages. An untrusted local user can cause a denial of service of Linux guests in Hyper-V virtualization environments. Dmitry Monakhov reported a race condition flaw the Linux ext4 filesystem that can expose stale data. An unprivileged user could exploit this flaw to cause an information leak. Various other issues were also addressed.
