CVE-2023-53669 tcp: fix skb_copy_ubufs() vs BIG TCP

In the Linux kernel, the following vulnerability has been resolved: tcp: fix skbcopyubufs vs BIG TCP David Ahern reported crashes in skbcopyubufs caused by TCP tx zerocopy using hugepages, and skb length bigger than 68 KB. skbcopyubufs assumed it could copy all payload using up to MAXSKBFRAGS...

CVE-2023-53669

The CVE-2023-53669 entry concerns the Linux kernel where skb_copy_ubufs() crashes when BIG TCP allows large skbs (up to ~512 KB) and zerocopy is used with hugepages. The root cause is skb_copy_ubufs() assuming payload could be copied using up to MAX_SKB_FRAGS order-0 pages; this breaks when BIG T...
