Descriptions

The ext4_group_add function in fs/ext4/resize.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not properly initialize the group descriptor during a resize (aka resize2fs) operation, which might allow local users to cause a denial of service (OOPS) by arranging for crafted values to be present in available memory.

La función ext4_group_add en fs/ext4/resize.c en el kernel de Linux v2.6.27 anteriores a v2.6.27.19 y v2.6.28 anteriores a v2.6.28.7 no inicializa de forma adecuada el descriptor de grupo durante una operación de cambio de tamaño (también conocido como resize2fs), que podría permitir a los usuarios locales, provocar una denegación de servicio (OOPS) organizando valores manipulados, para estar en la memoria disponible.
