This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

igb: Do not bring the device up after non-fatal error

Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal")

changed igb_io_error_detected() to ignore non-fatal pcie errors in order

to avoid hung task that can happen when igb_down() is called multiple

times. This caused an issue when processing transient non-fatal errors.

igb_io_resume(), which is called after igb_io_error_detected(), assumes

that device is brought down by igb_io_error_detected() if the interface

is up. This resulted in panic with stacktrace below.
