 - 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. (CVE-2024-49977)
