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

Bluetooth: MGMT: fix crash in set_mesh_sync and set_mesh_complete

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

Another crash is in set_mesh_complete() due to double list_del via
mgmt_pending_valid + mgmt_pending_remove.

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

As mgmt_pending_valid removes the cmd from list, use mgmt_pending_free,
and also report status on error.
