Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A divide-by-zero flaw exists in the
tcf skbedit hash() function. This occurs when the requested range covers all possible u16 queue IDs (for example, queue mapping is 0 and queue mapping max is U16 MAX), causing the inclusive range size calculation for mapping mod to equal 65536. Because this value cannot be represented in a u16, it wraps to 0, leading to a system crash during the modulo operation in the tcf skbedit hash() function.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
