CVE-2018-19985

Publication date 24 December 2018

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

Cvss 3 Severity Score

4.6 · Medium

Score breakdown

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.

From the Ubuntu Security Team

Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not properly validate metadata received from the device. A physically proximate attacker could use this to cause a denial of service (system crash).
