CVE-2018-19985 (opens in a new tab)How to fix?
Upgrade RHEL:8 kernel-doc to version 0:4.18.0-147.el8 or higher.
This issue was patched in RHSA-2019:3517.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-doc package and not the kernel-doc package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds (OOB) read that potentially allows arbitrary read in the kernel address space.
