In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: fix dma queue left shift overflow issue
When queue number is > 4, left shift overflows due to 32 bits
integer variable. Mask calculation is wrong for MTL_RXQ_DMA_MAP1.
If CONFIG_UBSAN is enabled, kernel dumps below warning:
