AI-suggested

Red Hat currently does not provide a mitigation or patch that meets its criteria for ease of use, deployment, applicability, or stability. Users should be aware that exploitation requires local user interaction to extract a crafted archive, and typical Red Hat environments use GNU tar rather than BusyBox tar for general extraction tasks, minimizing exposure. Monitoring Red Hat advisories for future updates or fixes is recommended.

Description

CVE-2026-124745 is a vulnerability in BusyBox's tar utility where deferred hardlink targets are improperly resolved across symbolic links pointing outside the intended extraction directory. This flaw allows an attacker to craft an archive that can overwrite arbitrary files on the system during extraction. The vulnerability is rated as moderate severity because exploitation requires local user interaction to extract a specially crafted archive, and typically requires subsequent extraction operations to achieve unauthorized file modification. In Red Hat environments, exposure is minimal since BusyBox tar is mainly used in constrained environments like initramfs or recovery images, while GNU tar is the standard for general extraction tasks. No mitigation or fix currently meets Red Hat's criteria for deployment and stability.
