CVE-2007-5966: Integer overflow in the hrtimer_start function in kernel/hrtimer.c in the Linux kernel before 2.6.23.10 all...

Security readout for executives and security teams

This is an old Linux kernel flaw where a local user could trigger an integer overflow in high-resolution timer handling. Successful abuse could crash the system or potentially run code with kernel-level impact. The main business risk is legacy or embedded Linux remaining on affected kernels. Exposure is most likely on unsupported legacy Linux systems, appliances, or vendor platforms that shipped kernels older than 2.6.23.10. Vendor advisories in the bundle include Debian, Red Hat, Mandriva, rPath, and VMware-related references, so package-level validation matters. Prioritize remediation where old Linux systems still host sensitive workloads or allow local user access. This is a legacy issue, but kernel-level impact means exposed unsupported systems should not be accepted without documented risk ownership. Mitigation focus: Upgrade affected Linux kernels to fixed vendor-supported versions.; Apply relevant distribution or platform errata for Debian, Red Hat, Mandriva, rPath, or VMware.; Prioritize hosts that allow untrusted local users or shared shell access..
