411 vulnerabilities classified as CWE-404 (不恰当的资源关闭或释放). AI Chinese analysis included.
CWE-404 represents a critical resource management weakness where software fails to properly release or incorrectly frees allocated resources, such as memory, file handles, or network connections, before they are reused. This flaw typically leads to resource exhaustion, causing application crashes, denial of service, or system instability as available resources dwindle. Attackers often exploit this by triggering repeated allocations without corresponding releases, effectively starving the system of necessary assets. To mitigate this risk, developers must implement rigorous lifecycle management, ensuring every allocated resource has a corresponding release mechanism. This involves using structured cleanup routines, leveraging language-specific garbage collection or smart pointers, and accounting for all execution paths, including error conditions and timeouts, to guarantee resources are consistently returned to the pool for safe reuse.
