CWE-191

Allowed

Integer Underflow (Wrap or Wraparound)

Abstraction: Base · Status: Draft

API response cwe.mitre.org

The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.

728 vulnerabilities reference this CWE, most recent first.

Title
Crash in `max_pool3d` when size argument is 0 or negative
Summary
TensorFlow is an open source platform for machine learning. In affected versions the Keras pooling layers can trigger a segfault if the size of the pool is 0 or if a dimension is negative. This is due to the TensorFlow's implementation of pooling operations where the values in the sliding window are not checked to be strictly positive. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.

CVE-2021-37706 (GCVE-0-2021-37706)

Vulnerability from cvelistv5 – Published: 2021-12-22 00:00 – Updated: 2025-11-04 16:09

Title
Potential integer underflow upon receiving STUN message in PJSIP
Summary
PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In affected versions if the incoming STUN message contains an ERROR-CODE attribute, the header length is not checked before performing a subtraction operation, potentially resulting in an integer underflow scenario. This issue affects all users that use STUN. A malicious actor located within the victim’s network may forge and send a specially crafted UDP (STUN) message that could remotely execute arbitrary code on the victim’s machine. Users are advised to upgrade as soon as possible. There are no known workarounds.

Title
WEIDMUELLER: WLAN devices affected by Denial-of-Service vulnerability
Summary
In Weidmueller Industrial WLAN devices in multiple versions an exploitable denial-of-service vulnerability exists in ServiceAgent functionality. A specially crafted packet can cause an integer underflow, triggering a large memcpy that will access unmapped or out-of-bounds memory. An attacker can send this packet while unauthenticated to trigger this vulnerability.
