CVE-2010-4243: fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory by...

Security readout for executives and security teams

This is an old Linux kernel local denial-of-service flaw. A local user could consume memory in a way the kernel's out-of-memory handling did not properly account for, potentially making the host unstable or unavailable. Exposure is mainly legacy Linux systems running kernels before 2.6.37, or downstream vendor kernels without the backported fix. Red Hat and VMware advisories in the bundle indicate vendor-tracked updates existed. Treat as a legacy availability risk. Prioritize internet-facing multi-user systems, shared hosting, jump boxes, and unsupported servers where local users or workloads are not fully trusted. Mitigation focus: Upgrade to a vendor kernel containing the CVE-2010-4243 fix.; Check Red Hat, VMware, or distribution advisories for backported kernel fixes.; Retire or isolate unsupported Linux systems that cannot receive kernel updates..
