A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. NOTE: this is related to an issue in the Linux kernel before 2.6.31, when the kernel routing cache is disabled, involving an uninitialized pointer and a panic.

CWE
Deadlock
mitre_cwe·CVSS 2.1
[LOW] CWE-833 Deadlock
CWE-833: Deadlock
The product contains multiple threads or executable segments that are waiting for each other to release a necessary lock, resulting in deadlock.
Modes of Introduction:
Phase: Implementation
Common Consequences:
Scope: Availability. Impact: DoS: Resource Consumption (CPU), DoS: Resource Consumption (Other), DoS: Crash, Exit, or Restart. Each thread of execution will "hang" and prevent tasks from completing. In some cases, CPU consumption may occur if a lock check occurs in a tight loop.
Detection Methods:
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
CWE
Improper Locking
mitre_cwe
CWE-667 Improper Locking
CWE-667: Improper Locking
The product does not properly acquire or release a lock on a resource, leading to unexpected resource state changes and behaviors.
Locking is a type of synchronization behavior that ensures that multiple independently-operating processes or threads do not interfere with each other when accessing the same resource. All processes/threads are expected to follow the same steps for locking. If these steps are not followed precisely - or if no locking is done at all - then another process/thread could modify the shared resource in a way that is not visible or predictable to the original process. This can lead to data or memory corruption, denial of service, etc.
