CVE-2019-19770

Priority
Description
** DISPUTED ** 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.
Notes
sbeattieno fix from upstream as of 2020/04/22, though proposed
patches are working their way through the review process.
