Common Weakness Enumeration

CWE-128

Wrap-around Error

Wrap around errors occur whenever a value is incremented past the maximum value for its type and therefore "wraps around" to a very small, negative, or undefined value.

CVE-2026-54905 (GCVE-0-2026-54905)

Vulnerability from cvelistv5 – Published: 2026-06-24 15:42 – Updated: 2026-06-24 16:41
VLAI
Title
concurrent-ruby: `ReentrantReadWriteLock` read-count overflow grants a write lock without exclusivity
Summary
concurrent-ruby is a modern concurrency tools for Ruby. Prior to 1.3.7, Concurrent::ReentrantReadWriteLock can incorrectly grant a write lock after one thread acquires the read lock 32,768 times. The lock stores a thread's local read and write hold counts in one integer. The low 15 bits are used for the read hold count, and bit 15 is used as WRITE_LOCK_HELD. After 32,768 reentrant read acquisitions, the local read count crosses into the write-lock bit. try_write_lock then treats the thread as already holding a write lock and returns true without setting the global RUNNING_WRITER bit. This breaks the core mutual-exclusion guarantee: the caller is told it has a write lock, but other threads can still hold or acquire read locks at the same time. This vulnerability is fixed in 1.3.7.

Mitigation

Phases:

Description:

  • Requirements specification: The choice could be made to use a language that is not susceptible to these issues.
Mitigation

Phase: Architecture and Design

Description:

  • Provide clear upper and lower bounds on the scale of any protocols designed.
Mitigation

Phase: Implementation

Description:

  • Perform validation on all incremented variables to ensure that they remain within reasonable bounds.
CAPEC-92: Forced Integer Overflow

This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
