When a program encounters certain out\u2011of\u2011memory conditions it fails to guard against a null pointer, which can cause the application to crash. This flaw is a classic instance of CWE\u2011476 and can be used to trigger a denial of service by terminating the LiteIDE process.", "risk_and_exploitability": "The CVSS score is 6.7, indicating moderate severity, while the EPSS score is less than 1% and the vulnerability is not listed in the CISA KEV catalog. No remote exploitation vector is documented, so the risk is chiefly local or for users who run the application in an unmanaged environment. The low EPSS suggests that the likelihood of exploitation is low, but the impact on availability is high if an attacker can force the application to crash."}}}}, "created": "2026-01-27T20:17:01.769705+00:00", "updated": "2026-04-18T02:30:15.867183+00:00", "vendors": ["visualfc", "visualfc$PRODUCT$liteide"]}
