Summary
[none]
Details

In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfsremove 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 debugfscreate_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
