Descriptions

The ring_buffer_resize function in kernel/trace/ring_buffer.c in the profiling subsystem in the Linux kernel before 4.6.1 mishandles certain integer calculations, which allows local users to gain privileges by writing to the /sys/kernel/debug/tracing/buffer_size_kb file.

La función ring_buffer_resize en kernel/trace/ring_buffer.c en el subsistema de creación de perfiles del kernel de Linux en versiones anteriores a 4.6.1 no maneja adecuadamente ciertos cálculos de entero, lo que permite a usuarios locales obtener privilegios escribiendo en el archivo /sys/kernel/debug/tracing/buffer_size_kb.
