Descriptions
In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to a right data structure.
En el kernel de Linux versiones 5.0.21 y 5.3.11, montando una imagen de sistema de archivos btrfs diseñada, al realizar algunas operaciones y luego haciendo una llamada de sistema syncfs puede conllevar a un uso de la memoria previamente liberada en la función try_merge_free_space en el archivo fs/btrfs/free-space-cache.c porque el puntero en una estructura de datos izquierda puede ser el mismo que el puntero en una estructura de datos derecha.
