          "details": "This issue is a reachable-assertion bug confined to libsndfile’s MP3 encoder close path, which at worst aborts the calling process (denial of service) and has no confidentiality or integrity impact. It is only reachable when an application actively performs MPEG Layer III encoding on attacker‑supplied audio—typically via a user‑initiated conversion—so the “network” vector applies only if a service explicitly exposes MP3 transcoding of untrusted inputs. In centrally managed enterprise VM/server environments where libsndfile is present as a library and no network‑facing MP3 transcoding workflow is exposed, practical exploitability is low and this CVE can be safely deprioritized.",
