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 icevsicfgrxq and reallocated again with iceallocrxbuf. kfree on rxbuf caused leak of already mapped DMA. Reallocate ZC with xdpbuf struct, when BPF program loads. Reallocate back to rxbuf, when BPF program unloads. If BPF program is loaded/unloaded and XSK pools are created, reallocate RX queues accordingly in XDPSETUPXSKPOOL 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
