CWE-191
AllowedInteger Underflow (Wrap or Wraparound)
Abstraction: Base · Status: Draft
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
Lack of buffer clearing before reuse may result in incorrect system behavior.
Summary
The Honeywell Experion PKS
and OneWireless WDM
contains an Integer Underflow
vulnerability
in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to a Communication Channel Manipulation, which could result in a failure during subtraction allowing remote code execution.
Honeywell recommends updating to the most recent version of
Honeywell Experion PKS:520.2 TCU9 HF1 and 530.1 TCU3 HF1 and OneWireless: 322.5 and 331.1.
The affected Experion PKS products are C300 PCNT02, C300 PCNT05, FIM4, FIM8, UOC, CN100, HCA, C300PM, and C200E. The Experion PKS versions affected are from 520.1 through 520.2 TCU9 and from 530 through 530 TCU3. The OneWireless WDM affected versions are 322.1 through 322.4 and 330.1 through 330.3.

Title
Eclipse ThreadX NetX Duo component HTTP server single PUT request integer underflow
Summary
In NetX HTTP server functionality of Eclipse ThreadX NetX Duo before
version 6.4.3, an attacker can cause an integer underflow and a
subsequent denial of service by writing a very large file, by specially
crafted packets with Content-Length in one packet smaller than the data
request size of the other packet. A possible workaround is to disable
HTTP PUT support.
This issue follows an incomplete fix of CVE-2025-0727

Title
Eclipse ThreadX NetX Duo HTTP server single PUT request integer underflow
Summary
In NetX HTTP server functionality of Eclipse ThreadX NetX Duo before
version 6.4.2, an attacker can cause an integer underflow and a
subsequent denial of service by writing a very large file, by specially
crafted packets with Content-Length smaller than the data request size. A
possible workaround is to disable HTTP PUT support.

CVE-2024-56375 (GCVE-0-2024-56375)

Summary
An integer underflow was discovered in Fort 1.6.3 and 1.6.4 before 1.6.5. A malicious RPKI repository that descends from a (trusted) Trust Anchor can serve (via rsync or RRDP) a Manifest RPKI object containing an empty fileList. Fort dereferences (and, shortly afterwards, writes to) this array during a shuffle attempt, before the validation that would normally reject it when empty. This out-of-bounds access is caused by an integer underflow that causes the surrounding loop to iterate infinitely. Because the product is permanently stuck attempting to overshuffle an array that doesn't actually exist, a crash is nearly guaranteed.

Title
Suricata segfault on StreamingBufferSlideToOffsetWithRegions
Summary
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.8, a specially crafted TCP stream can lead to a very large buffer overflow while being zero-filled during initialization with memset due to an unsigned integer underflow. The issue has been addressed in Suricata 7.0.8.
