Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel's team module related to port management. Specifically, a double-free condition can occur within the
team queue override port prio changed() function when a port is disabled and a priority change is subsequently attempted. This occurs because the function incorrectly attempts to delete a port that has already been removed from the list. The issue was identified through syzkaller testing, resulting in a kernel bug related to list corruption.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
