DescriptionNVD

A flaw was found in GNU Binutils. This heap-based buffer overflow vulnerability, specifically an out-of-bounds read in the bfd linker, allows an attacker to gain access to sensitive information. By convincing a user to process a specially crafted XCOFF object file, an attacker can trigger this flaw, potentially leading to information disclosure or an application level denial of service.

AnalysisAI

Information disclosure and denial-of-service in GNU Binutils' BFD linker (ld) arises from an out-of-bounds heap read when parsing malformed XCOFF object files. A local attacker who convinces a user to link or otherwise process a specially crafted XCOFF file can leak adjacent heap memory (CWE-125) or crash the linking process. Tracked by Red Hat across RHEL 6 through 10 and OpenShift 4; no public exploit is identified and EPSS exploitation probability is negligible (0.01%, 2nd percentile).

Technical ContextAI

GNU Binutils provides the BFD (Binary File Descriptor) library that underpins the ld linker, objdump, and related tools. The flaw is in BFD's handling of XCOFF, the extended COFF object/executable format historically used on IBM AIX and PowerPC targets. CWE-125 (out-of-bounds read) indicates BFD reads beyond an allocated heap buffer-typically because a length, count, or offset field inside the attacker-controlled XCOFF structure is trusted without bounds validation-so the parser dereferences memory past the end of the allocation while iterating headers, symbol tables, or relocation entries. Affected products per CPE are Red Hat Enterprise Linux 10, 8, 7, and 6 distributions that ship the vulnerable binutils package, with OpenShift Container Platform 4 also tagged.

RemediationAI

Apply the vendor-released binutils update: on Red Hat systems install the errata RHSA-2026:33527 (https://access.redhat.com/errata/RHSA-2026:33527) via 'dnf update binutils', and on Ubuntu/Debian apply the distribution binutils security updates as they publish (medium priority). The specific fixed package version was not provided in the source data-obtain the exact patched build from the distro advisory rather than assuming a version. Because exploitation requires processing an attacker-supplied XCOFF object file, the primary compensating control where patching must be deferred is to avoid linking or inspecting untrusted object files: restrict CI/build pipelines to vetted source inputs, sandbox toolchain invocations (containers/seccomp) when handling externally supplied objects, and disallow ld/objdump runs against files from untrusted origins. XCOFF is an AIX/PowerPC format rarely needed on x86 Linux, so blocking or refusing XCOFF inputs in build tooling has minimal side effects for typical ELF-only workflows.
