Summary
Bluetooth: MGMT: fix crash in set_mesh_sync and set_mesh_complete
Details

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

Bluetooth: MGMT: fix crash in setmeshsync and setmeshcomplete

There is a BUG: KASAN: stack-out-of-bounds in setmeshsync due to memcpy from badly declared on-stack flexible array.

Another crash is in setmeshcomplete() due to double listdel via mgmtpendingvalid + mgmtpending_remove.

Use DEFINE_FLEX to declare the flexible array right, and don't memcpy outside bounds.

As mgmtpendingvalid removes the cmd from list, use mgmtpendingfree, and also report status on error.
