In the Linux kernel, the following vulnerability has been resolved:
ice: Fix DMA mappings leak
Fix leak, when user changes ring parameters.
During reallocation of RX buffers, new DMA mappings are created for
those buffers. New buffers with different RX ring count should
substitute older ones, but those buffers were freed in ice_vsi_cfg_rxq
and reallocated again with ice_alloc_rx_buf. kfree on rx_buf caused
leak of already mapped DMA.
Reallocate ZC with xdp_buf struct, when BPF program loads. Reallocate
back to rx_buf, when BPF program unloads.
If BPF program is loaded/unloaded and XSK pools are created, reallocate
RX queues accordingly in XDP_SETUP_XSK_POOL handler.
Steps for reproduction:
while :
do
	for ((i=0; i<=8160; i=i+32))
	do
		ethtool -G enp130s0f0 rx $i tx $i
		sleep 0.5
		ethtool -g enp130s0f0
	done
done
