Details

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 order-0 pages. This assumption broke when BIG TCP was able to put up to 512 KB per skb. We did not hit this bug at Google because we use CONFIGMAXSKBFRAGS=45 and limit gsomaxsize to 180000. A solution is to use higher order pages if needed. v2: add missing _GFP_COMP, or we leak memory.
