In the Linux kernel, the following vulnerability has been resolved:

ionic: fix kernel panic due to multi-buffer handling

Currently, the ionic_run_xdp() doesn't handle multi-buffer packets
properly for XDP_TX and XDP_REDIRECT.
When a jumbo frame is received, the ionic_run_xdp() first makes xdp
frame with all necessary pages in the rx descriptor.
And if the action is either XDP_TX or XDP_REDIRECT, it should unmap
dma-mapping and reset page pointer to NULL for all pages, not only the
first page.
But it doesn't for SG pages. So, SG pages unexpectedly will be reused.
It eventually causes kernel panic.
