CVE-2019-15213

Published: 19 August 2019

An issue was discovered in the Linux kernel before 5.2.3. There is a use-after-free caused by a malicious USB device in the drivers/media/usb/dvb-usb/dvb-usb-init.c driver.

Priority

Low

CVSS 3 base score: 4.6

Status

Notes

Setting priority to low since this issue requires a malicious USB
device to be inserted into the system
Ben Hutchings noticed that commit 6cf97230cd5f ("media: dvb: usb: fix
use after free in dvb_usb_device_exit"), which is mentioned in the CVE
references for this issue, likely doesn't fix the problem. See the lore
reference above for details. I think Ben is correct and have adjusted our
break-fix metadata to use the break commit that he pointed out.

unfixed upstream as of 2022-01-27
