名前: Improper Resource Locking

The product must have exclusive access to a resource, but it does not lock or does not correctly lock that resource.

クラス： Not Language-Specific (Undetermined)

一般的な結果

スコープ 影響 可能性
Integrity
Availability		Modify Application Data, DoS: Instability, DoS: Crash, Exit, or Restart

注記：When a resource is not properly locked, an attacker could modify the resource while it is being operated on by the product. This might violate the product's assumption that the resource will not change, potentially leading to unexpected behaviors.

参考文献 説明

CVE-2022-20141

Chain: an operating system kernel has insufficient resource locking (CWE-413) leading to a use after free (CWE-416).

潜在的な緩和策

Phases : Architecture and Design
Use a non-conflicting privilege scheme.
Phases : Architecture and Design // Implementation
Use synchronization when locking a resource.

検出方法

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
有効性 : High

脆弱性マッピングノート

理由 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
コメント : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
