Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The vulnerability is related to a race condition in the Linux kernel's ice component, which can cause a crash when updating Traffic Classes (TCs) with more configurations than allocated queues. This issue arises when the number of allocated queues is less than the number of Traffic Classes, or when the TC configuration is updated due to Link Layer Discovery Protocol (LLDP) after initially setting fewer queues. The
ice vsi cfg tc() function fails and leaves dirty num txq/rxq and tc cfg in the vsi, resulting in invalid pointer access. This can lead to a general protection fault and potentially cause a denial-of-service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
