Vulnerability Description

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix a buffer overflow in mgmt_mesh_add() Smatch Warning: net/bluetooth/mgmt_util.c:375 mgmt_mesh_add() error: __memcpy() 'mesh_tx->param' too small (48 vs 50) Analysis: 'mesh_tx->param' is array of size 48. This is the destination. u8 param[sizeof(struct mgmt_cp_mesh_send) + 29]; // 19 + 29 = 48.
