CWE-667 Improper Locking: Deadlocks, Double Unlocks and Races
Locks that are skipped, held forever or released twice cause deadlocks, crashes and memory corruption. See the failure patterns and how to lock safely.
Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
Locks that are skipped, held forever or released twice cause deadlocks, crashes and memory corruption. See the failure patterns and how to lock safely.
Using a resource before it is ready or after it is released causes corruption and crashes. Know the lifecycle of every resource you touch.
Variables and buffers left unset or set wrong can leak memory contents, skip security checks or crash a program. Learn where it bites and how to prevent it.
Files, memory, locks and objects all have a lifecycle. CWE-664 is the parent of the bugs that happen when code ignores it, from leaks to use after free.
Calling a function that keeps internal state from a signal handler or a second thread can corrupt memory or crash the program. Use reentrant calls or add locking.
Shared resources touched by several threads or processes without proper coordination cause corruption, crashes and security bugs. Here is how to spot and fix it.
Some file names are aliases for things that are not files. When software treats them as ordinary files, it can leak source code or crash. This is CWE-66.
Design flaws are expensive to fix after the code ships. What CWE-657 covers, the CVEs MITRE ties to it, and how to review designs earlier.
Hidden form fields, hard-coded keys and secret algorithms fail once someone looks. Real examples from MITRE and what to use instead.
