Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition vulnerability in the Linux kernel's ice component can cause a dead-lock when an interface leaves and immediately rejoins a LAG. This occurs because the
ice plug aux dev() function is called from the ice service task() context, creating an auxiliary device and taking the associated device lock, while the ice unplug aux dev() function, called by the notifier under RTNL lock, attempts to take the same lock, resulting in a dead-lock. The vulnerability can be exploited by an attacker to cause a denial-of-service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
