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

net: fix NULL pointer in skbsegmentlist

Commit 3a1296a38d0c ("net: Support GRO/GSO fraglist chaining.") introduced UDP listifyed GRO. The segmentation relies on fraglist being untouched when passing through the network stack. This assumption can be broken sometimes, where fraglist itself gets pulled into linear area, leaving frag_list being NULL. When this happens it can trigger following NULL pointer dereference, and panic the kernel. Reverse the test condition should fix it.
