Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the Linux kernel, specifically with the pktgen module. It involves the use of
cpus read lock() in pg net init() and the firing of WARN ON(smp processor id() != cpu) in pktgen thread worker() during tests. To resolve this, cpus read lock() and cpus read unlock() should be used around the for each online cpu(cpu) loop. Additionally, WARN ON ONCE() should be used to avoid a possible syslog flood.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
