Descriptions
The Linux Kernel version 3.18 contains a dangerous feature vulnerability in modify_user_hw_breakpoint() that can result in crash and possibly memory corruption. This attack appear to be exploitable via local code execution and the ability to use ptrace. This vulnerability appears to have been fixed in git commit f67b15037a7a50c57f72e69a6d59941ad90a0f0f.
El kernel de Linux en su versión 3.18 contiene una vulnerabilidad de funcionalidad peligrosa en modify_user_hw_breakpoint() que puede resultar en un cierre inesperado y en una posible corrupción de memoria. El ataque parece ser explotable mediante la ejecución de código local y la capacidad de usar ptrace. La vulnerabilidad parece haber sido solucionada en el commit git con ID f67b15037a7a50c57f72e69a6d59941ad90a0f0f.
An address corruption flaw was discovered in the Linux kernel built with hardware breakpoint (CONFIG_HAVE_HW_BREAKPOINT) support. While modifying a h/w breakpoint via 'modify_user_hw_breakpoint' routine, an unprivileged user/process could use this flaw to crash the system kernel resulting in DoS OR to potentially escalate privileges on a the system.
