  "title": "net: appletalk: fix NULL pointer dereference in aarp_send_ddp()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: appletalk: fix NULL pointer dereference in aarp_send_ddp()  aarp_send_ddp() calls atalk_find_dev_addr(dev) in the LocalTalk fast path without checking for NULL. When the device has no AppleTalk interface configured (dev-\u003Eatalk_ptr == NULL), this leads to a NULL pointer dereference at the at-\u003Es_net access.   KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]  RIP: 0010:aarp_send_ddp (net/appletalk/aarp.c:552 (discriminator 2))  Call Trace:   \u003CTASK\u003E   atalk_sendmsg (net/appletalk/ddp.c:1715)   __sys_sendto (net/socket.c:2265 (discriminator 1))   __x64_sys_sendto (net/socket.c:2272)   do_syscall_64 (arch/x86/entry/syscall_64.c:94)   entry_SYSCALL_64_after_hwframe (arch/x86/entry/entry_64.S:121)  Add a NULL check consistent with the other callers of atalk_find_dev_addr().",
