Static code analysis and peer reviews enforce strong input validation and error handling, preventing improperly validated inputs from causing system instability, data exposure, or privilege escalation. In the event of successful exploitation, process isolation limits the impact of excessive sequential memory allocation by restricting memory use per process, preventing any single process from exhausting system resources.

"text": "OpenShift Container Platform (OCP) starting from 4.10 stream is already compiled in the patched version of Go, hence is not affected by this vulnerability.The vulnerability has been rated as moderate instead of high because the vulnerability can only result in a minor denial of service.\n\nWithin regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-1325: Improperly Controlled Sequential Memory Allocation vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.\n\nAccess to the platform is granted only after successful hard token-based multi-factor authentication (MFA) and is governed by least privilege to ensure only authorized users and roles can execute or modify code. Static code analysis and peer reviews enforce strong input validation and error handling, preventing improperly validated inputs from causing system instability, data exposure, or privilege escalation. In the event of successful exploitation, process isolation limits the impact of excessive sequential memory allocation by restricting memory use per process, preventing any single process from exhausting system resources. Finally, the platform uses memory protection mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) to reduce the risk of memory allocation-based attacks.",
