Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An issue in the Linux kernel can lead to a deadloop within the rcu read unlock() function due to softirq. This occurs because recursion-protection code was removed from the rcu read unlock() function, allowing a deadloop to be triggered in raise softirq irqoff() when ftrace is enabled. The problem specifically involves the rcu read unlock special() function.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
