      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: tvlv: reject oversized TVLV packets\n\nbatadv_tvlv_container_ogm_append() builds a TVLV packet section from\nthe tvlv.container_list. The total size of this section is computed by\nbatadv_tvlv_container_list_size(), which sums the sizes of all registered\ncontainers.\n\nThe return type and accumulator in batadv_tvlv_container_list_size() were\nu16. If the accumulated size exceeds U16_MAX, the value wraps around,\ncausing the subsequent allocation in batadv_tvlv_container_ogm_append()\nto be undersized. The memcpy-style copy that follows would then write\nbeyond the end of the allocated buffer, corrupting kernel memory.\n\nFix this by widening the return type of batadv_tvlv_container_list_size()\nto size_t. In batadv_tvlv_container_ogm_append(), check the computed length\nagainst U16_MAX before proceeding, and bail out as if the allocation had\nfailed when the limit is exceeded.",
