AI-suggested

Currently, no mitigation or patch is available that meets Red Hat's criteria for ease of use, deployment, applicability, or stability. Standard Red Hat Enterprise Linux systems are not significantly exposed due to the use of util-linux instead of BusyBox. Users of minimal environments or containers relying on BusyBox should avoid probing untrusted filesystem images or attached storage devices. Monitor Red Hat advisories for any future updates or fixes.

Description

CVE-2026-124746 is an integer overflow vulnerability in the volume_id component of BusyBox used in Red Hat Hardened Images. It occurs when calculating buffer boundaries while probing filesystem metadata, leading to a crash of utilities like blkid, findfs, or mount. This results in a denial of service (DoS) that prevents the system from resolving or mounting storage devices. The vulnerability requires a local attacker to provide a specially crafted filesystem image on an attached storage device. Standard Red Hat Enterprise Linux systems are largely unaffected as they use util-linux instead of BusyBox for these operations. The flaw mainly impacts minimal environments, rescue shells, or specialized containers using BusyBox for filesystem probing. No fix is currently available that meets Red Hat's criteria for deployment and stability.
