Summary
skbuff: Account for tail adjustment during pull operations
Details

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

skbuff: Account for tail adjustment during pull operations

Extending the tail can have some unexpected side effects if a program uses a helper like BPFFUNCskbpulldata to read partial content beyond the head skb headlen when all the skbs in the gso fraglist are linear with no headfrag -

Fix this by marking these skbs as GSO_DODGY so segmentation can handle the tail updates accordingly.
