Summary
In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file). NOTE: Linux kernel developers dispute this issue as not being an issue with debugfs, instead this is an issue with misuse of debugfs within blktrace

NOTA: Los desarrolladores del kernel de Linux disputan este problema como no un problema con debugfs, sino que es un problema con el mal uso de debugfs dentro de blktrace."
