Reproduced under KASAN:    BUG: KASAN: slab-use-after-free in pep_get_sb+0x234/0x3b0   Read of size 1 at addr ff11000105510f50 by task repro/157    pep_get_sb+0x234/0x3b0    pipe_handler_do_rcv+0x5f7/0xa10    pep_do_rcv+0x203/0x410    __sk_receive_skb+0x471/0x4a0    phonet_rcv+0x5b3/0x6c0    __netif_receive_skb+0xcc/0x1d0  Refetch the header with skb_header_pointer() after pskb_may_pull(), so the possibly stale pointer is no longer dereferenced. There are better ways to solve this, but, this is the less instrusive one.",
