Security readout for executives and security teams
CVE-2011-0891 is a local denial-of-service issue in HP-UX kernel-related OS-Core.CORE2-KRN fileset on HP-UX B.11.23 and B.11.31. A user with local access could disrupt system availability through unspecified vectors. The public bundle does not provide CVSS, technical details, or confirmed exploitation. Exposure is limited to organizations still running HP-UX B.11.23 or B.11.31 with the affected OS-Core.CORE2-KRN fileset. Risk depends on whether untrusted or many users have local shell, application, batch, or administrative access to those systems. Prioritize if HP-UX supports business-critical workloads or many local users. This is not described as remote code execution, but denial of service on legacy UNIX infrastructure can still create material operational disruption. Mitigation focus: Identify HP-UX B.11.23 and B.11.31 hosts.; Review HP advisory HPSBUX02646 for supported remediation.; Apply vendor-approved patches or updates where applicable..
