DEBIAN-CVE-2026-15813

Type: advisorySource: OSV1 source record

A vulnerability was found in the network packet de-fragmentation engine of kronosnet (Version affected <= 1.34). The internal reassembly code does not properly validate sequence numbers of incoming payload fragments. An attacker can exploit this lack of verification by transmitting malformed packets with corrupted sequence parameters. Under specific conditions, this forces the packet processing layer to parse data outside the designated bounds of the internal memory structures, causing an out-of-bounds memory access or heap corruption. This behavior can result in sudden application crashes or system instability.
