CVE-2019-19947

Published: 24 December 2019

In the Linux kernel through 5.4.6, there are information leaks of uninitialized memory to a USB device in the drivers/net/can/usb/kvaser_usb/kvaser_usb_leaf.c driver, aka CID-da2311a6385c.

From the Ubuntu Security Team

It was discovered that the Kvaser CAN/USB driver in the Linux kernel did not properly initialize memory in certain situations. A local attacker could possibly use this to expose sensitive information (kernel memory).

Notes

AuthorNote
tyhicks
I don't think that the Fixes tag in patch is correct and that the
info leaks were possible since the initial inclusion of the driver
Priority

Low

CVSS 3 base score: 4.6
