CVE-2026-88357: n/a
nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code. Specially crafted network input can cause byte-buffer addresses at odd offsets to be cast to uint16_t or wider integer pointers and directly dereferenced without alignment checks. This results in undefined behavior and can cause process termination in UBSan-instrumented builds or on strict-alignment architectures, leading to denial of service.
AI Analysis
Technical Summary
The vulnerability in nDPI 5.1.0 arises from the DNS dissector and serializer deserialization code where byte-buffer addresses at odd offsets are cast to uint16_t or wider integer pointers without alignment checks. This improper memory access can cause undefined behavior, including process crashes, especially on architectures enforcing strict alignment or when using UBSan-instrumented builds. The flaw can be triggered by specially crafted network input, leading to denial of service.
Potential Impact
Exploitation of this vulnerability can cause the affected process to terminate unexpectedly, resulting in denial of service. There is no indication of code execution or data corruption beyond process termination. No known exploits are reported in the wild.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider mitigating exposure by limiting untrusted network input to the affected nDPI component or running it in a constrained environment to reduce impact of potential crashes.
