Summary
In the Linux kernel, the following vulnerability has been resolved:
net: sxgbe: free TX rings on RX allocation failure
When RX descriptor ring allocation fails, init_dma_desc_rings() only frees the partially allocated RX rings and returns. The TX rings that were allocated earlier in the same function are leaked.
Rearrange error labels to clean up TX rings upon RX failures.
