CVE-2011-1593: Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel before 2.6.38.4...

Security readout for executives and security teams

CVE-2011-1593 is a Linux kernel flaw that can let a local user crash a vulnerable system. It is not described as remote code execution or privilege escalation in the provided sources. Business impact is availability: shared servers, multi-user systems, and hosted environments are the main concern. Exposure is most likely on Linux systems running kernels before 2.6.38.4, or vendor kernels that had not yet incorporated the corresponding upstream or distribution fixes. Single-user systems with no untrusted local access have lower practical exposure. Treat this as a moderate availability risk. It should be remediated through normal kernel patching, with higher urgency for systems where untrusted or semi-trusted users can run local processes. Mitigation focus: Identify Linux hosts running affected pre-2.6.38.4 or unpatched vendor kernels.; Apply kernel updates from the relevant Linux distribution vendor.; Review Ubuntu USN-1146-1 and Red Hat RHSA-2011:0927 where applicable..
