Descriptions

In the Linux kernel 5.3.11, mounting a crafted btrfs image twice can cause an rwsem_down_write_slowpath use-after-free because (in rwsem_can_spin_on_owner in kernel/locking/rwsem.c) rwsem_owner_flags returns an already freed pointer,

En el kernel de Linux versión 5.3.11, montar una imagen btrfs especialmente diseñada dos veces puede causar un uso de la memoria previamente liberada de la función rwsem_down_write_slowpath porque (en la función rwsem_can_spin_on_owner en el archivo kernel/locking/rwsem.c) la función rwsem_owner_flags devuelve un puntero ya liberado.
