Detailsinfo

A vulnerability was found in Eukaryot Sonic3air up to 26.03.28.0. It has been classified as problematic. This affects the function ReceivedPacketCache::enqueuePacket of the component ReceivedPacketCache. The manipulation of the argument mUniquePacketID with an unknown input leads to a allocation of resources vulnerability. CWE is classifying the issue as CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. This is going to have an impact on availability. The summary by CVE is:

Sonic 3 A.I.R. before commit 2492d18 contains an unbounded memory allocation vulnerability in ReceivedPacketCache::enqueuePacket() that allows unauthenticated remote attackers to crash the server process by sending a crafted UDP packet with mUniquePacketID set to the maximum uint32 value. The mUniquePacketID field is read directly from the UDP wire-format packet header without bounds checking, causing the server to allocate one CacheItem per missing packet ID gap, exhausting available host memory and propagating an uncaught std::bad_alloc exception to std::terminate().

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-66733 since 07/27/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1499 for this issue.
