9DescriptionNVD
A flaw was found in GNU Binutils. This vulnerability, a heap-based buffer overflow, specifically an out-of-bounds read, exists in the bfd linker component. An attacker could exploit this by convincing a user to process a specially crafted malicious XCOFF object file. Successful exploitation may lead to the disclosure of sensitive information or cause the application to crash, resulting in an application level denial of service.
AnalysisAI
Out-of-bounds heap read in the BFD linker (ld) component of GNU Binutils allows information disclosure or an application-level crash when a victim is induced to process a crafted XCOFF object file. Affected across Red Hat Enterprise Linux 6 through 10 (and OpenShift Container Platform 4), exploitation requires user interaction and local file processing - there is no public exploit identified at time of analysis, and the EPSS probability is negligible (0.01%, 2nd percentile).
Technical ContextAI
GNU Binutils provides the BFD (Binary File Descriptor) library that underpins the GNU linker (ld), assembler, and object-file tooling. The flaw is in BFD's parser for XCOFF - the eXtended Common Object File Format used historically on IBM AIX/PowerPC - where malformed structure or section/symbol-table fields are trusted without adequate bounds checking. The root cause class is CWE-125 (Out-of-bounds Read): the linker reads memory beyond the bounds of a heap-allocated buffer while parsing attacker-controlled object metadata, which can leak adjacent heap contents into output/diagnostics or dereference invalid memory and abort. Per the supplied CPE data the affected vendor packaging is Red Hat Enterprise Linux 6/7/8/10 (cpe:2.3:a:red_hat:red_hat_enterprise_linux_*), reflecting the binutils package shipped with those distributions rather than a standalone upstream-only product.
RemediationAI
Apply the vendor binutils update for your distribution: on Red Hat Enterprise Linux install the package from RHSA-2026:33527 (https://access.redhat.com/errata/RHSA-2026:33527) via 'yum update binutils' / 'dnf update binutils'; track the corresponding Ubuntu and Debian binutils security updates for those platforms - patch status here is 'Patch available per vendor advisory' (exact upstream tagged release version is not stated in the provided data, so cite your distribution's errata version rather than an invented number). As a compensating control until patched, do not run ld/binutils tooling on untrusted or attacker-supplied object files: in CI/build systems, restrict linking to inputs from trusted sources and isolate build steps that consume third-party object/archive files in sandboxed or ephemeral containers (trade-off: added pipeline complexity). Because the bug is in XCOFF parsing specifically, environments that never link XCOFF (the common case on x86_64 Linux) have inherently lower exposure, but this is not a guaranteed mitigation and patching remains the reliable fix.
