CVE-2024-26462 is a memory leak vulnerability found in Kerberos 5 (krb5) version 1.21.2. Specifically, the vulnerability exists within the /krb5/src/kdc/ndr.c file, potentially leading to resource exhaustion. Although the CVSS score is 5.5, indicating a medium severity, the SOCRadar Vulnerability Risk Score (SVRS) is 30, suggesting a relatively low immediate threat level. This score reflects that, while present, the vulnerability may not be actively exploited or associated with known threat actors at this time. The vulnerability, categorized as CWE-401, allows an attacker to potentially exhaust system memory by repeatedly triggering the memory leak. However, the low SVRS score suggests that actively patching this vulnerability is less urgent compared to vulnerabilities with higher scores. Addressing this memory leak will improve system stability.
