The first one  \nwill proceed to then free the stateid which leads to either  \nuse-after-free or decrementing already zeroed counter. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"21 Oct 2024\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-10-21T22:43:18.000000Z"}]}
