CVE-2026-6846 Details
Description
A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable.
A heap-buffer-overflow vulnerability has been identified in Red Hat Binutils versions through 2.46.1. This flaw occurs when the linker processes a specially crafted XCOFF (Extended Common Object File Format) object file, leading to heap corruption. A local attacker could exploit this vulnerability to execute arbitrary code, potentially allowing the execution of unauthorized commands. Additionally, the vulnerability could cause a denial-of-service by making the system unavailable.
Users can upgrade to Binutils versions 2.47 or later, which includes the fix for this vulnerability. Instructions for applying the update are available on the Red Hat Images site.
