GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2021-22332 (GCVE-0-2021-22332)

Vulnerability from cvelistv5 – Published: 2021-04-28 12:10 – Updated: 2024-08-03 18:37
VLAI
Summary
There is a pointer double free vulnerability in some versions of CloudEngine 5800, CloudEngine 6800, CloudEngine 7800 and CloudEngine 12800. When a function is called, the same memory pointer is copied to two functional modules. Attackers can exploit this vulnerability by performing a malicious operation to cause the pointer double free. This may lead to module crash, compromising normal service.
