Gnu Binutils
CVE-2026-3441
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.
What this means for your business
- It affects Gnu Binutils. It matters if your company, or a supplier that handles your data, runs it.
- An attacker can use it only with access to the machine itself, without a login, but only after tricking someone into an action such as opening a file or a link.
- FIRST's prediction model gives it a 0.2% chance of attack attempts being seen in the next 30 days, ranking above 8% of all known flaws.
What to do
- 1Check whether your company or your suppliers run Gnu Binutils, and which version. The affected versions are listed further down this page.
- 2If you do, apply the vendor's fix. A patch or vendor advisory has been published.
