CVE-2022-48690

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
