uvm_fault: rtable_satoplen (2)
Status: fixed on 2019/04/04 06:33
Reported-by: syzbot+7e4426b400fe6ee4afc1@syzkaller.appspotmail.com
Fix commit: 575ef11475ca Add a more strict rtm_hdrlen size check. Make sure that at least struct rt_msghdr bytes are passed in. Also return a failure from rtm_xaddrs() if rti_addrs has bad flags or run out of space. Ok bluhm@
