CVE-2025-11413
Description
A flaw was found in binutils. Processing a specially crafted object file with the ld linker can trigger an out-of-bounds write in the bfd_putl64 function in the bfd/libbfd.c file due to an improper check, causing a crash and resulting in a denial of service.
Statement
This issue is classified with a low severity primarily because binutils is not typically exposed to untrusted inputs in most environments, limiting the possibility of exploitation. Additionally, this out-of-bounds write is only triggered during the parsing of a specially crafted file, requiring an attacker to convince a user to process this file with ld-new. Furthermore, binutils does not handle privileged operations, meaning that exploitation is unlikely to lead to system compromise or escalation of privileges. Also, the impact is limited to the application itself, without affecting the broader system or network security.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Red Hat CVSS v3 Score Explanation
An attacker needs to convince a user into running the ld linker with a specially crafted file, the attacker does not need any access or privileges to exploit this vulnerability. To reflect this condition, the privileges required metric is set to none and the user interaction metric is set to required. Furthermore, an attacker does not have the ability to completely deny service, as the crash will only occur when a specially crafted file is processed, legitimate files can be processed normally. Additionally, this issue can cause an out-of-bounds write of only 1 byte. To reflect this condition, the integrity and availability metrics are set to low.
Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
