Name of the Vulnerable Software and Affected Versions kronosnet versions prior to 1.35

Description The network packet de-fragmentation engine contains a flaw where the internal reassembly code fails to properly validate sequence numbers of incoming payload fragments. An attacker can transmit malformed packets with corrupted sequence parameters, forcing the packet processing layer to parse data outside the designated bounds of internal memory structures. This leads to out-of-bounds memory access or heap corruption, which may cause application crashes or system instability.

Recommendations Update kronosnet to version 1.35 or later.
