Title
bpf: Fix out-of-bounds write in trie_get_next_key()
Summary
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 has full paths from the root to leaves. For example, consider a trie with max_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.

No network-facing code path processes remote data through trie_get_next_key().\nAC:L - The overflow is fully deterministic \u2014 the attacker builds the trie with keys 0x00/0 \u2026 0x00/max_prefixlen and issues one GET_NEXT_KEY with prefixlen == max_prefixlen. No race, no timing dependency, and the attacker also chooses key_size so the allocation sits exactly on a kmalloc bucket boundary, and can repeat the trigger arbitrarily to groom the heap.\nPR:L - Creating the map nominally needs CAP_BPF, but `bpf_token_capable()` honors ns_capable() against a BPF-token user namespace, so a delegated bpffs mount grants it to an unprivileged container process; furthermore `bpf_obj_get()` performs only a file-permission check and `map_get_next_key()` requires only FMODE_CAN_READ, so an unprivileged process holding or opening an existing pinned LPM_TRIE map fd can trigger the write with no capability at all.\nUI:N - Exploitation is entirely self-contained in the attacker\u0027s own process \u2014 map creation, element insertion, and the GET_NEXT_KEY call. No victim action of any kind is required.\nS:U - The out-of-bounds write corrupts kernel slab memory within the same kernel security authority; it is a standard local privilege-escalation surface rather than a crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The 8-byte heap overflow overwrites the first field of the adjacent slab object with a pointer to attacker-controlled data, which for the many kmalloc-64/128/256 objects that begin with a pointer yields a fake-object read primitive and, via freelist corruption, arbitrary kernel memory disclosure.\nI:H - This is a controllable out-of-bounds heap write of a valid kernel pointer at a precisely chosen slab bucket boundary, repeatable at will \u2014 a classic path to SLUB freelist corruption, arbitrary write, and control-flow hijack for privilege escalation.\nA:H - Corrupting the head of an adjacent slab object or a SLUB freelist pointer reliably produces kernel oops/panic, and the trigger can be issued repeatedly by any process holding a readable LPM_TRIE map fd."

Las llamadas posteriores a trie_get_next_key con _key con .prefixlen = 8 hacen que se escriban 9 nodos en la pila de nodos con tama\u00f1o 8."
