CVE-2025-11414 is an out-of-bounds read vulnerability identified in GNU Binutils version 2.45, specifically within the get_link_hash_entry function located in the bfd/elflink.c source file of the linker component. Binutils is a widely used collection of binary tools essential for compiling and linking software on Unix-like systems. The vulnerability arises due to improper bounds checking when accessing internal data structures during the linking process, allowing an attacker with local access and low privileges to read memory beyond intended boundaries. This can lead to information disclosure or potentially cause the linker to crash, affecting the integrity and availability of the build process. The attack vector is local, requiring the attacker to have the ability to execute code on the affected system, but no user interaction or elevated privileges beyond low-level local access are necessary. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no active exploits have been reported in the wild. The issue is addressed by upgrading to GNU Binutils version 2.46, which includes a patch (commit aeaaa9af6359c8e394ce9cf24911fec4f4d23703) that corrects the bounds checking logic in the affected function.

For European organizations, the impact of CVE-2025-11414 primarily concerns development and build environments where GNU Binutils 2.45 is in use. Since Binutils is fundamental in software compilation and linking, exploitation could lead to information leakage of sensitive memory contents or cause build failures, potentially disrupting software development pipelines. While the vulnerability does not allow remote exploitation, insider threats or compromised local accounts could leverage this flaw to gain unauthorized information or destabilize critical build systems. This could affect organizations in sectors with stringent software integrity requirements, such as finance, telecommunications, and critical infrastructure. Disruptions in build processes may delay software releases or updates, impacting operational continuity. Additionally, any leaked information could aid attackers in further exploitation or reconnaissance activities.

Organizations should immediately upgrade GNU Binutils to version 2.46 or later to remediate this vulnerability. Where upgrading is not immediately feasible, restricting local access to build servers and developer workstations running vulnerable Binutils versions is critical. Implement strict access controls and monitoring to detect unauthorized local activity. Employ sandboxing or containerization for build environments to limit the impact of potential exploitation. Regularly audit and update development toolchains to ensure they are free from known vulnerabilities. Additionally, integrate vulnerability scanning into the software supply chain to detect outdated or vulnerable components proactively. Educate developers and system administrators about the risks of local vulnerabilities and the importance of timely patching.
