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.

[MEDIUM] Linux kernel regression
Title: Linux kernel regression
Summary: USN 4115-1 introduced a regression in the Linux kernel.
USN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu
18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update,
a regression was introduced that caused a kernel crash when handling
fragmented packets in some situations. This update addresses the issue.
We apologize for the inconvenience.

kernel: oob memory read in hso_probe in drivers/net/usb/hso.c
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.
A flaw was found in the Linux kernel in the function hso_probe() which reads if_num value from the USB device (as an u8) and uses it without a length check to index an array, resulting in an OOB memory read in hso_probe() or hso_get_config_data(). An attacker with a forged USB device and physical access to a system (needed to connect such a device) can cause a system crash and a denial of service.
