CVE-2025-11412 is a vulnerability discovered in GNU Binutils version 2.45, affecting the linker component, specifically the function bfd_elf_gc_record_vtentry in the source file bfd/elflink.c. The flaw results from an out-of-bounds read condition, where the function improperly accesses memory beyond the intended buffer boundaries. This can lead to information disclosure or potential corruption of internal data structures. The vulnerability requires local access with low privileges, meaning an attacker must have some level of access to the system to trigger the flaw. No user interaction or elevated authentication is necessary beyond local presence. The vulnerability does not impact availability or cause code execution but can compromise confidentiality and integrity by leaking sensitive memory contents. The issue has been publicly disclosed, and a patch has been committed (commit ID 047435dd988a3975d40c6626a8f739a0b2e154bc) to address the problem. GNU Binutils is widely used in software development and build processes across many operating systems, making this vulnerability relevant to a broad range of environments. The CVSS 4.0 base score is 4.8, reflecting a medium severity due to the local attack vector and limited impact scope.

The primary impact of CVE-2025-11412 is the potential for unauthorized disclosure of memory contents due to an out-of-bounds read in the linker component of GNU Binutils. This can lead to leakage of sensitive information such as cryptographic keys, passwords, or proprietary code fragments if an attacker has local access. Although the vulnerability does not allow remote exploitation or privilege escalation directly, it poses a risk in multi-user environments, shared development systems, or build servers where untrusted users have local access. The integrity of the linking process could also be indirectly affected if corrupted memory is read, potentially causing build failures or incorrect binaries. Organizations relying heavily on GNU Binutils in their development pipelines or embedded systems could face confidentiality breaches or operational disruptions. The absence of known exploits in the wild reduces immediate risk, but public disclosure increases the likelihood of future exploitation attempts.

To mitigate CVE-2025-11412, organizations should promptly apply the official patch identified by commit 047435dd988a3975d40c6626a8f739a0b2e154bc to GNU Binutils version 2.45. Until patched, restrict local access to systems running vulnerable versions, especially on shared or multi-user environments. Implement strict access controls and monitoring to detect unusual linker usage or memory access patterns. Use containerization or sandboxing techniques for build environments to limit the impact of potential exploitation. Regularly audit and update development tools and dependencies to maintain security hygiene. Additionally, consider employing memory protection mechanisms such as AddressSanitizer during development to detect similar issues proactively. Educate developers and system administrators about the risks of local vulnerabilities in build tools and enforce least privilege principles to minimize attack surfaces.
