In the Linux kernel, the following vulnerability has been resolved:
net: vertexcom: mse102x: Fix possible double free of TX skb
The scope of the TX skb is wider than just mse102x_tx_frame_spi(), so in case the TX skb room needs to be expanded, we should free the the temporary skb instead of the original skb. Otherwise the original TX skb pointer would be freed again in mse102x_tx_work(), which leads to crashes:
