NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-modules-partner package and not the kernel-debug-modules-partner package as distributed by Centos.

In the Linux kernel, the following vulnerability has been resolved:

net: stmmac: Fix zero-division error when disabling tc cbs

The commit b8c43360f6e4 ("net: stmmac: No need to calculate speed divider when offload is disabled") allows the "port_transmit_rate_kbps" to be set to a value of 0, which is then passed to the "div_s64" function when tc-cbs is disabled. This leads to a zero-division error.

When tc-cbs is disabled, the idleslope, sendslope, and credit values the credit values are not required to be configured. Therefore, adding a return statement after setting the txQ mode to DCB when tc-cbs is disabled would prevent a zero-division error.
