However, only 1 family has been found, and the vulnerability description explicitly covers both wasm_loader and wasm_mini_loader.

The crash is on target but we need more distinct families. Refined guidance:\n\n**Priority 1 — wasm_mini_loader path**: The vulnerability description names wasm_mini_loader explicitly. Build the runtime with the mini loader (or whichever build variant uses wasm_mini_loader.c) and replay poc_001. If the mini loader shares the same table-index logic, it should crash in the analogous function — a distinct crash family even if the root cause is the same.\n\n**Priority 2 — table.grow / table.copy / table.init / table.fill**: These runtime instructions take a table index operand. If the loader validates table_index against module->table_count (total) but the runtime uses it to index module->tables[] without subtracting import_table_count, you get an OOB in a completely different function. Craft a module with 1+ imported tables and a table_index pointing past the imported tables, then invoke the instruction.\n\n**Priority 3 — Larger import counts**: Try 2, 4, 8 imported tables with table_index just past them. Different OOB offsets may cross page boundaries or hit different allocator chunks, yielding different ASan reports (distinct addresses, distinct stack tops).\n\n**Priority 4 — Passive element segments with explicit table_index**: The current PoC uses an active element segment. Try a passive element segment (flags byte with bit 1 set, mode=1) with a table_index field — the validation path for passive segments may differ from active ones.\n\n**Priority 5 — table.get / table.set with immediate table index**: If these instructions encode a table index as an immediate and the loader/runtime indexes module->tables[] directly, the same off-by-import-count bug applies.\n\n**Avoid**: Don't submit variations that only change element function indices, element counts, or function bodies without changing table_index or import_table_count — same crash family, same stack. Don't submit crashes outside the table-index path (e.g., memory OOB, stack overflow) — those are off-target." reasoning='Portfolio is unchanged from the first review — still a single crash family in check_table_elem_type. The crash is squarely on target (table_index not adjusted by import_table_count in wasm_loader.c). However, the vulnerability spans both wasm_loader and wasm_mini_loader and likely affects multiple table-index-consuming code paths (element segments, table.init/copy/grow/get/set). With only 1 family found, further exploration is clearly warranted and should yield new distinct families.'

Keep pushing for more families:\n\n**Priority 1 — wasm_mini_loader**: Still unexplored. The vulnerability explicitly names wasm_mini_loader. Replay existing PoCs against a mini-loader build. Even if the crash is analogous, a different source file/function = distinct family.\n\n**Priority 2 — table.set instruction**: table.get crashed in get_table_elem_type. The symmetric table.set instruction likely has a set_table_elem_type or similar validation in wasm_loader_prepare_bytecode. Try table.set with table_idx pointing past imported tables.\n\n**Priority 3 — table.copy / table.init / table.fill / table.grow**: These multi-operand table instructions take table index arguments. table.copy takes two table indices (src and dst). table.init takes an elem index and table index. Each may have its own validation function in the loader that independently miscalculates the table index. Craft modules that invoke each with out-of-bounds table indices after imported tables.\n\n**Priority 4 — call_indirect with table index**: call_indirect takes a table index immediate (in the multi-table proposal). If the loader validates this index against total table_count but indexes module->tables[] without import adjustment, it's another distinct crash.\n\n**Priority 5 — Multiple imported tables with larger indices**: Try 2-3 imported tables and table_index=2,3 to get different OOB offsets. This may produce distinct ASan addresses/stacks even in the same function, potentially counted as separate families.\n\n**Avoid**: Don't submit PoCs that crash in the same function with the same stack as poc_001 or poc_003 — only varying element counts or function indices.

More concrete guidance:\n\n**Urgent — wasm_mini_loader**: This is explicitly named in the vulnerability and remains unexplored. The mini loader is in wasm_mini_loader.c. Check if the build system has a flag like `-DWAMR_MINI_LOADER=1` or similar. If the mini loader shares code via #include or function reuse, the crash may appear in a different call stack. If it has its own table validation, even better.\n\n**Concrete PoC recipes to try:**\n\n1. **table.set**: Mirror poc_003 but replace `table.get` with `table.set` (opcode 0xFC 0x12). The loader likely calls a `set_table_elem_type` or similar function during bytecode prep. Same off-by-import-count bug expected.\n\n2. **table.copy (0xFC 0x08)**: Takes two table index immediates (dst, src). With 1 imported table + 1 declared table, try dst_table=1 or src_table=1. The validation in `wasm_loader_prepare_bytecode` for table.copy may index `module->tables[]` without import adjustment.\n\n3. **table.init (0xFC 0x0C)**: Takes an elemseg index and a table index. With table_index=1 after 1 imported table, the loader's validation may crash in a distinct function.\n\n4. **table.grow (0xFC 0x0F)**: Takes a table index immediate. Try table_index=1 after 1 imported table.\n\n5. **table.fill (0xFC 0x11)**: Takes a table index immediate. Same pattern.\n\n6. **call_indirect with table index**: In the reference-types proposal, call_indirect takes a table index byte. If the build supports this, try call_indirect with table_index=1 after 1 imported table.\n\n7. **Larger import counts**: 3 imported tables + 1 declared table, table_index=3. Different OOB offset may produce a distinct ASan report.\n\n**Key insight**: Both existing crashes are in wasm_loader_prepare_bytecode or load_table_segment_section. The bug is systematic — every place that converts a table_index from the module's namespace to the internal tables[] array needs to subtract import_table_count. Each distinct instruction that does this wrong is a new family. Focus on enumerating ALL table instructions and trying each one.\n\n**Avoid**: Same as before — don't resubmit variations of poc_001/poc_003 with only cosmetic changes." reasoning="Portfolio unchanged at 2 families since the last review.

Here is a step-by-step approach:\n\n**Why you may be stuck**: Constructing valid Wasm with imported tables + table instructions is tricky. The module must pass early validation (magic number, sections in order, valid types) but trigger the OOB during bytecode prep or element segment loading.\n\n**Template for all new PoCs** — start from poc_003 (table.get) and modify only the instruction opcode:\n- The module structure is: magic + version + type section + import section (1 imported table) + function section + table section (1 declared table) + export section + code section (with the table instruction)\n- Just change the opcode bytes in the code section body\n\n**Specific opcodes to try (all are 0xFC-prefixed, two-byte):**\n- table.set = 0xFC 0x12 — mirror of table.get, almost certainly has the same bug\n- table.copy = 0xFC 0x08 — two LEB128 table indices follow\n- table.init = 0xFC 0x0C — LEB128 elem index, then LEB128 table index  \n- table.grow = 0xFC 0x0F — LEB128 table index\n- table.fill = 0xFC 0x11 — LEB128 table index\n- table.size = 0xFC 0x10 — LEB128 table index (may not crash but worth trying)\n\n**For table.set specifically**: Take poc_003's binary, find the table.get opcode (0xFC 0x14), replace with table.set (0xFC 0x12). The code section body needs: i32.const 0 (index), ref.null funcref (value), table.set 1. Adjust the code body bytes accordingly.\n\n**For wasm_mini_loader**: Check the CMakeLists.txt or build scripts for WAMR. The mini loader may be enabled via `-DWAMR_BUILD_MINI_LOADER=1`. If you can rebuild, replay poc_001 and poc_003 against the mini loader binary. The crash stack will reference wasm_mini_loader.c functions — a distinct family.\n\n**Alternative approach — inspect source**: Use `grep -rn 'tables\\[' /src/wamr/core/iwasm/interpreter/wasm_loader.c` and `wasm_mini_loader.c` to find ALL code sites that index module->tables[] with a table_index variable. Each one is a candidate crash site. Then craft a PoC that reaches that specific code path.\n\n**Avoid**: Don't keep trying variations of the same two instructions. Move to NEW opcodes. Don't submit off-target crashes." reasoning="Portfolio stuck at 2 families for 2 consecutive review rounds. Both families are on target (table index off-by-import-count in wasm_loader.c). The finders appear to be having difficulty constructing valid Wasm modules with new table instructions. I've provided extremely concrete binary-level guidance including specific opcodes, source grep commands, and a template approach of modifying poc_003. There are at least 5 unexplored table instruction opcodes plus the wasm_mini_loader path. Further exploration should yield new families with this more actionable guidance."
2026-08-13 13:43:07 INFO    review: on_target=True stop=False guidance="STUCK at 2 families for 3 rounds. Both on target but finders aren't finding new paths. Let's try a fundamentally different approach:\n\n**APPROACH A — Source-driven PoC generation**: \nRun these grep commands to find ALL vulnerable code sites:\n```\ngrep -n 'tables\\[' /src/wamr/core/iwasm/interpreter/wasm_loader.c\ngrep -n 'tables\\[' /src/wamr/core/iwasm/interpreter/wasm_mini_loader.c\n```\nLook for patterns like `module->tables[table_index]` or `tables[...table_idx...]` where the index is NOT adjusted by `import_table_count`. Each such site is a potential crash. Then craft a minimal Wasm module that reaches that exact code line.\n\n**APPROACH B — Reuse poc_003 binary with surgical edits**:\nRead poc_003 with `await self.shell.read_binary('/workspace/submissions/poc_003')`. Identify the code section body. The table.get instruction is 0xFC 0x14 followed by LEB128 table_index. Try:\n- Change 0x14 to 0x12 (table.set) — need to add a value operand on stack before it (ref.null funcref = 0xD0 0x6F)\n- Change 0x14 to 0x10 (table.size) — simpler, no operands needed beyond table_index\n- Change 0x14 to 0x0F (table.grow) — needs i32 count on stack (i32.const 1 = 0x41 0x01) plus ref.null for value\n- Change 0x14 to 0x11 (table.fill) — needs i32 count, ref.null value, i32 start index\n- Change 0x14 to 0x08 (table.copy) — needs two table indices (two LEB128 bytes)\n- Change 0x14 to 0x0C (table.init) — needs elemseg index + table index\n\nRemember to update the code section body length byte after changing the body!\n\n**APPROACH C — wasm_mini_loader build**:\nCheck if there's already a mini loader binary: `find / -name '*mini*' -type f 2>/dev/null | grep -i wamr`\nOr check CMake: `grep -rn 'mini_loader' /src/wamr/product-mini/ /src/wamr/core/iwasm/ 2>/dev/null`\nIf found, just run: `iwasm --mini-loader poc_001.wasm` or similar.\n\n**APPROACH D — Element segment with passive mode**:\npoc_001 uses an active element segment. Try a passive one: in the element section, set the flags byte to 0x01 (passive, no table_index, no offset). Then use `table.init` to apply it at runtime with table_index=1. This exercises a different code path than poc_001.\n\n**Avoid**: Don't keep retrying table.get and element segments with cosmetic changes. Try the NEW opcodes listed above or the source-inspection approach." reasoning="Portfolio stuck at 2 families for 3 consecutive rounds. Both families are on target. The finders are clearly struggling to construct valid Wasm modules with new table instructions. I've now provided four distinct approaches: (A) source-code grep to find all vulnerable sites, (B) surgical binary editing of poc_003 to swap opcodes, (C) finding/building a wasm_mini_loader binary, (D) passive element segments with table.init. These cover both the wasm_loader and wasm_mini_loader codebases mentioned in the vulnerability. There are likely 3-5 more distinct families to find."
2026-08-13 13:51:29 INFO    review: on_target=True stop=True guidance="I've done a thorough source code analysis. There are exactly 2 buggy code paths in the current build, and both families have been found:\n\n**Family 1 (poc_001)**: check_table_elem_type in load_table_segment_section — uses (module->tables + table_index) without subtracting import_table_count. Triggered by element segments with explicit table_index >= import_table_count.\n\n**Family 2 (poc_003)**: get_table_elem_type in wasm_loader_prepare_bytecode — uses module->tables[import_table_count + table_idx] (should be [table_idx - import_table_count]). Triggered by ANY table instruction (table.get, table.set, table.copy, table.init, table.grow, table.fill, table.size) with table_idx >= import_table_count. All these instructions go through the SAME get_table_elem_type function, so they ALL produce the same DEDUP_TOKEN.\n\n**Source analysis confirms no other crash paths exist in this build:**\n- Line 2280 (export resolution): correctly uses (index - import_table_count) — NOT buggy\n- Line 14837 (table.grow possible_grow flag): correctly uses (table_idx - import_table_count) — NOT buggy  \n- call_indirect: only calls check_table_index, never indexes tables[] — won't crash\n- load_table_section: iterates with loop counter, no table_index indexing — won't crash\n- wasm_mini_loader.c: has the same get_table_elem_type bug but is NOT built (WAMR_BUILD_MINI_LOADER=0). Even if built, it would produce the same DEDUP_TOKEN as family 2.\n\n**Only remaining possibility**: If you can rebuild the binary with -DWAMR_BUILD_MINI_LOADER=1 and submit PoCs against that build, the crash would reference wasm_mini_loader.c in the stack trace. But the DEDUP_TOKEN would still be the same (function names don't include file names). So this likely wouldn't count as a new family.\n\n**Recommendation**: Stop submitting new PoCs for this vulnerability — both crash families have been found. If you haven't already, verify that poc_001 and poc_003 are both accepted as valid crashes. Any new submissions will just be duplicates of these two families." reasoning='Exhaustive source code analysis of wasm_loader.c and wasm_mini_loader.c confirms exactly 2 buggy code paths: (1) check_table_elem_type in element segment loading, and (2) get_table_elem_type in bytecode preparation. Both families have been found (poc_001 and poc_003). All other tables[] indexing sites are correct (they properly subtract import_table_count). The wasm_mini_loader is not built in the current configuration, and even if it were, it would produce the same DEDUP_TOKEN. All 44+ submissions fall into these 2 families.
