      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: tt: prevent TVLV OOB check overflow\n\nA TT unicast TVLV contains the number of VLANs stored in it. This number is\nan u16 and gets multiplied by the size of the struct\nbatadv_tvlv_tt_vlan_data (8 bytes). The size can therefore overflow the u16\nused to store the tt_vlan_len. All additional safety checks to prevent\nout-of-bounds access of the TVLV buffer are invalid due to this overflow.\n\nUsing size_t prevents this overflow and ensures that the safety checks\ncompare against the actual buffer requirements.",
