This issue was patched in RHSA-2019:3517.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-perf package and not the python3-perf package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

fs/ext4/extents.c in the Linux kernel through 5.1.2 does not zero out the unused memory region in the extent tree block, which might allow local users to obtain sensitive information by reading uninitialized data in the filesystem.
