## Technical details

A NULL pointer dereference occurs in NetX Duo's MSRP implementation when the attribute table is exhausted, potentially triggered by network input or application logic that creates many MSRP attributes without proper bounds checking. An attacker with network access or local code execution could trigger the crash by exhausting the MSRP attribute table, resulting in a denial of service condition.
