GSD-2021-21724

Vulnerability from gsd - Updated: 2023-12-13 01:23
Details
A ZTE product has a memory leak vulnerability. Due to the product's improper handling of memory release in certain scenarios, a local attacker with device permissions repeatedly attenuated the optical signal to cause memory leak and abnormal service. This affects: ZXR10 8900E, all versions up to V3.03.20R2B30P1.
