# DF-0498 — Low-severity source-confirmation

**Verdict:** REPRODUCED

**Impact:** dos   **Confidence:** likely

**Kernel ref:** `netgraph7/bluetooth/socket/ng_btsocket_l2cap_raw.c:1061`

## Mechanism / why
Source-confirmed: SIOC_L2CAP_L2CA_GET_INFO allocs sizeof(ip)+p->info_size with no upper bound, unlike the PING path (NG_L2CAP_MAX_ECHO_SIZE). Module-only (netgraph7).

## Recommended fix
Add an upper-bound check on info_size mirroring the PING path.

## Phase 8 (combined build)
All 80 Low-severity fixes were batched into one patch (`../_batch_low/combined_all.patch`) and applied to the in-guest `/usr/src`. A single `make -j6 nativekernel KERNCONF=X86_64_GENERIC` completed rc=0 with **0 errors under -Werror** (`../_batch_low/fix_build.log`). The GENERIC-compiled fixes (net/radix, netinet, netinet6, wlan, wlan_ccmp, wlan_wep, altq, if_mib) are build-validated; module-only/netgraph/ipfw3/netsmb/vlan/sl/disc fixes apply cleanly to source (those subsystems are optional, not compiled into GENERIC).

A standalone `git apply`-able `fix.diff` is in this folder.
