In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix out-of-bounds write in triegetnext_key()
triegetnextkey() allocates a node stack with size trie->maxprefixlen, while it writes (trie->maxprefixlen + 1) nodes to the stack when it has full paths from the root to leaves. For example, consider a trie with maxprefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ... 0x00/8 inserted. Subsequent calls to triegetnext_key with _key with .prefixlen = 8 make 9 nodes be written on the node stack with size 8.
