Description msiddiqu 2020-03-31 10:24:57 UTC 
A vulnerability was found in F2FS touch driver in kernel where there is a possible out of bounds
read due to improper input validation. This could lead to local information
disclosure with system execution privileges needed. User interaction is not
needed for exploitation.

Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1819149]
Comment 2 Justin M. Forbes 2020-03-31 13:56:41 UTC 
This was fixed for Fedora with the 5.1.12 stable kernel updates.
Comment 3 Alex 2020-04-08 11:36:31 UTC 
For F2FS (file system) that is disabled for all rhel* versions,
the configuration param that is disabled:
"# CONFIG_F2FS_FS is not set"
