NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-tools package and not the kernel-uek-tools package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

ext4_empty_dir in fs/ext4/namei.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference because ext4_read_dirblock(inode,0,DIRENT_HTREE) can be zero.
