Status: WontFix (was: Untriaged)
Upstream commit 4c41aa24baa4ed338 ("staging: ncpfs: memory corruption in ncp_read_kernel()"). Fixed in chromeos-4.4 with merge of v4.4.125. Fixed in chromeos-4.14 with merge of v4.14.31. IPX and with it NCPFS is not enabled in ChromeOS images, thus ChromeOS not affected. Assuming that Lakitu isn't affected either, marking as WontFix.
