Descriptions
In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c.
En el kernel de Linux versión 5.0.21, montar una imagen de sistema de archivos btrfs diseñada, realizar algunas operaciones y desmontarlas puede conllevar a un uso de la memoria previamente liberada en la función btrfs_queue_work en el archivo fs/btrfs/async-thread.c.
It was discovered that the btrfs implementation in the Linux kernel did not properly detect that a block was marked dirty in some situations. An attacker could use this to specially craft a file system image that, when unmounted, could cause a denial of service. It was discovered that the linux kernel did not properly validate certain mount options to the tmpfs virtual memory file system. A local attacker with the ability to specify mount options could use this to cause a denial of service. Various other issues were also addressed.
