Summary
In the Linux kernel, the following vulnerability has been resolved: net: lapb: increase LAPB_HEADER_LEN It is unclear if net/lapb code is supposed to be ready for 8021q. We can at least avoid crashes like the following : skbuff: skb_under_panic: text:ffffffff8aabe1f6 len:24 put:20 head:ffff88802824a400 data:ffff88802824a3fe tail:0x16 end:0x140 dev:nr0.2 ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:206 !
