Summary

CVE-2026-3441 is a medium-severity Out-of-bounds Read (CWE-125) vulnerability in Redhat Enterprise Linux. Its CVSS base score is 6.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-3441 is a heap-based buffer overflow vulnerability, specifically an out-of-bounds read, in the bfd linker component of GNU Binutils. This flaw affects GNU Binutils, a collection of binary utilities commonly used for manipulating object files and binaries across various Unix-like systems. Published on 2026-03-16, it is rated with a CVSS v3.1 base score of 6.1 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:L) and maps to CWE-125 (Out-of-bounds Read).

An attacker can exploit this vulnerability locally by convincing a user or administrator to process a specially crafted XCOFF object file using affected Binutils tools. No privileges are required (PR:N), but it demands low complexity and user interaction, such as opening or linking the malicious file. Successful exploitation enables high-impact confidentiality violations through access to sensitive information or low-impact application-level denial of service.

For mitigation details, security practitioners should refer to the Red Hat security advisory at https://access.redhat.com/security/cve/CVE-2026-3441 and the associated Bugzilla entry at https://bugzilla.redhat.com/show_bug.cgi?id=2443826, which provide guidance on patches and workarounds.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation directly finds out-of-bounds read flaws through static analysis, fuzzing, and dynamic bounds checks.

Secure engineering principles require bounds checking and memory-safe constructs that stop out-of-bounds reads from being introduced.

Process isolation confines the effects of an out-of-bounds read to the compromised process.

Input validation rejects malformed indices or lengths that would otherwise cause reads outside buffer bounds.

PR.PS-06 mostly match
prevents

Secure-development practices such as bounds checking and memory-safe languages directly prevent out-of-bounds reads.

ID.RA-01 partial match
prevents

Vulnerability scanning and recording can discover instances of out-of-bounds reads after code is deployed.

PR.PS-02 partial match

finds

Security testing in development and acceptance includes fuzzing and static analysis that detect out-of-bounds read defects before release.

A.8.15 Logging partial match
finds

Logging can record evidence of an out-of-bounds read but does not prevent the weakness itself.

prevents

Secure development life cycle mandates input validation and bounds checking that directly prevent out-of-bounds reads.

prevents

Application security requirements include explicit bounds and memory-safety specifications that mitigate buffer over-reads.

prevents

Secure system architecture and engineering principles require memory-safe design patterns and runtime protections against out-of-bounds access.

prevents

Secure coding standards explicitly forbid unsafe pointer arithmetic and mandate bounds-checked reads, eliminating CWE-125.
