Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description An integer overflow issue exists in the net/sched sch fq module when the "initial quantum" is configured with values greater than INT MAX. This overflow results in a negative value being assigned to "credit", potentially causing a CPU soft-lockup warning. The issue was identified through the use of the syzkaller script. Capping the "initial quantum" to INT MAX resolves the problem.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
