Threats Tagged 'cve-2026-15813'

This security update for kronosnet addresses three vulnerabilities: improper sanitization of sensitive memory that could expose encryption keys, improper verification of packet origins allowing ACL bypass via ID spoofing, and improper validation during fragment reassembly that may cause memory corruption or out-of-bounds access. These issues could lead to unauthorized access or memory safety problems. The severity is assessed as medium based on the described impacts. No affected versions or patch details are provided in the input data.

A vulnerability was found in kronosnet's (version <=1.34) cryptographic configuration management. The framework does not correctly zero-out or wipe sensitive memory segments after executing changes to its cryptographic configuration. This omission leaves raw encryption keys resident in memory after the associated structures are freed. A local attacker capable of leveraging memory disclosure techniques could exploit this flaw to retrieve the active encryption key, allowing them to decrypt cluster network communications or inject malicious packets to cause severe high-availability cluster instability.

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.
