Service degradation via malformed-message flood
Published Apr 1, 2026 · Updated Apr 1, 2026
Denial of service in Ericsson Packet Core Controller before 1.38 allows attackers to degrade service with crafted messages. Ericsson has not disclosed the message type, receiving network function, or invalid structure that the affected parser handles incorrectly. Exploitation requires adjacent-network access, no authentication, high complexity, and a large message volume; the reported impact is service degradation without confidentiality or integrity loss.
