CVE-2024-50262
Description
In the Linux kernel, the following vulnerability has been resolved:bpf: Fix out-of-bounds write in trie_get_next_key()trie_get_next_key() allocates a node stack with size trie->max_prefixlen,while it writes (trie->max_prefixlen + 1) nodes to the stack when it hasfull paths from the root to leaves. For example, consider a trie withmax_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ...0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with.prefixlen = 8 make 9 nodes be written on the node stack with size 8.
