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‑404.

Based on the provided references, it appears that the relibc library within the Redox OS project, particularly the commit 61f42d, is affected. This attribution is inferred from the repository links, as no vendor is explicitly listed.

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 indicates an exploitation probability of less than 1%, the vulnerability is not listed in KEV, and the CVSS score is 7.5, but the DoS impact can affect system availability and disrupt services.
