Service interruption via repeated-operation memory leak
Published May 29, 2020 · Updated Aug 4, 2024
Resource leak in listed Huawei CloudEngine and NetEngine firmware allows remote attackers to interrupt service over the device network. Huawei attributes the leak to improper memory management triggered by a series of operations but has not disclosed the affected component, operation sequence, or unreleased resource. The attacker needs network access to the device; the documented consequence is service interruption from memory exhaustion, with no confidentiality or integrity impact.
