This vulnerability (CVE-2026-19582) affects binutils 2.46.1 and prior versions used by Red Hat's Migration Toolkit for Containers. It is a stack buffer overflow caused by an out-of-bounds write when processing a crafted PE file. Exploitation requires local access and user interaction, such as opening a malicious file. The flaw can lead to arbitrary code execution, memory corruption, and denial of service. Red Hat's advisory classifies the impact as moderate and does not currently provide an official patch or remediation level. Users are advised to avoid opening untrusted PE files with binutils.

Successful exploitation can result in arbitrary code execution with the privileges of the user opening the crafted PE file, memory corruption, and potential denial of service due to crashes. The attack vector is local with low complexity and no privileges required, but user interaction is necessary. Red Hat rates the impact as moderate because exploitation requires local access or social engineering. There are no known exploits in the wild at this time.

Red Hat advises users not to open unknown or untrusted PE files using binutils. No official patch or fix is currently confirmed. Users should monitor the Red Hat advisory for updates on remediation status and apply fixes once available. Until then, avoiding untrusted files is the primary mitigation.
