The flaw is located in the DSO::mmap_and_copy function of the relibc library. A specially crafted shared library can cause the system to crash, resulting in a denial of service. The weakness is a memory corruption that manifests when the loader processes a malicious library, and it is classified as CWE‑122.

Affected components include the relibc library of the Redox OS project. The vulnerability is present in the commit identified by 61f42d and was addressed in a subsequent merge request. No other vendors or products are listed as impacted.

The exploit requires the ability to load or influence the loading of a malformed shared library. Because the flaw resides in a user‑space loader routine, the attack vector is likely local or through a compromised application that accepts user‑supplied libraries. EPSS data is not available, the vulnerability is not listed in KEV, and no CVSS score was supplied, but the DoS impact can affect system availability and disrupt services.
