Descriptions
Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel before 4.7.1 allows local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed.
Vulnerabilidad de uso después de liberación de memoria en la función disk_seqf_stop en block/genhd.c en el kernel de Linux en versiones anteriores a 4.7.1 permite a usuarios locales obtener privilegios aprovechando la ejecución de una cierta operación de parada incluso si la operación de arranque correspondiente hubiera fallado.
A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation.
