CVE-2021-21723

Some ZTE products have a DoS vulnerability. Due to the improper handling of memory release in some specific scenarios, a remote attacker can trigger the vulnerability by performing a series of operations, resulting in memory leak, which may eventually lead to device denial of service. This affects: ZXR10 9904, ZXR10 9908, ZXR10 9916, ZXR10 9904-S, ZXR10 9908-S; all versions up to V1.01.10.B12.
