Repeated failures can accumulate enough leaked data to exhaust available memory, potentially causing application crashes or degraded performance, and thereby leading to service disruption.

The EPSS score of less than 1\u202f% suggests a very low probability of exploitation at this time, and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires an attacker to trigger multiple failed HTTP interactions with a KMC client, either by controlling a malicious KMC server or by inducing network errors. The impact is limited to increased memory consumption and potential denial of service, with no direct compromise of data confidentiality or integrity."}}}}, "created": "2026-01-12T14:36:48.506532+00:00", "updated": "2026-04-18T19:30:08.952630+00:00", "vendors": ["nasa", "nasa$PRODUCT$cryptolib"]}
