CWE-362
Allowed-with-ReviewConcurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
Abstraction: Class · Status: Draft
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
2925 vulnerabilities reference this CWE, most recent first.
GHSA-998F-8276-5GR2
Vulnerability from github – Published: 2025-09-05 18:31 – Updated: 2025-11-26 00:30In the Linux kernel, the following vulnerability has been resolved:
net: kcm: Fix race condition in kcm_unattach()
syzbot found a race condition when kcm_unattach(psock) and kcm_release(kcm) are executed at the same time.
kcm_unattach() is missing a check of the flag kcm->tx_stopped before calling queue_work().
If the kcm has a reserved psock, kcm_unattach() might get executed between cancel_work_sync() and unreserve_psock() in kcm_release(), requeuing kcm->tx_work right before kcm gets freed in kcm_done().
Remove kcm->tx_stopped and replace it by the less error-prone disable_work_sync().

Mitigation
In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.
Mitigation
Use thread-safe capabilities such as the data access abstraction in Spring.
Mitigation
- Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.
- Additionally, this will minimize the amount of synchronization necessary and may even help to reduce the likelihood of a denial of service where an attacker may be able to repeatedly trigger a critical section (CWE-400).
Mitigation
When using multithreading and operating on shared variables, only use thread-safe functions.
Mitigation
Use atomic operations on shared variables. Be wary of innocent-looking constructs such as "x++". This may appear atomic at the code layer, but it is actually non-atomic at the instruction layer, since it involves a read, followed by a computation, followed by a write.
Mitigation
Use a mutex if available, but be sure to avoid related weaknesses such as CWE-412.
Mitigation
Avoid double-checked locking (CWE-609) and other implementation errors that arise when trying to avoid the overhead of synchronization.
Mitigation
Disable interrupts or signals over critical parts of the code, but also make sure that the code does not go into a large or infinite loop.
Mitigation
Use the volatile type modifier for critical variables to avoid unexpected compiler optimization or reordering. This does not necessarily solve the synchronization problem, but it can help.
Mitigation MIT-17
Strategy: Environment Hardening
Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
CAPEC-26: Leveraging Race Conditions
The adversary targets a race condition occurring when multiple processes access and manipulate the same resource concurrently, and the outcome of the execution depends on the particular order in which the access takes place. The adversary can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance, a race condition can occur while accessing a file: the adversary can trick the system by replacing the original file with their version and cause the system to read the malicious file.
CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
