Memory Safety: High
Multiple AVB AECP AEM command handler functions copied network packet
data into stack buffers via memcpy(buf, m, len) without validating
that len fits within the destination buffer. A crafted AVB packet with
an oversized length could overflow the stack buffer.
Added bounds validation before each memcpy in:
- cmd-available.c: handle_cmd_entity_available_milan_v12
- cmd-get-set-configuration.c: set and get configuration handlers
- cmd-get-set-sampling-rate.c: unsolicited, invalid response, and get handlers
- cmd-get-set-stream-format.c: get and set stream format handlers
- cmd-lock-entity.c: handle_cmd_lock_entity_milan_v12
This matches the bounds checking pattern already used in
cmd-get-set-control.c, cmd-get-set-clock-source.c, and
cmd-get-set-name.c.
