Buffer overflow in sysctl in the Linux Kernel 2.6 before 2.6.15 allows local users to corrupt user memory and possibly cause a denial of service via a long string, which causes sysctl to write a zero byte outside the buffer. NOTE: since the sysctl is called from a userland program that provides the argument, this might not be a vulnerability, unless a legitimate user-assisted or setuid scenario can be identified.

Security readout for executives and security teams

This is an old Linux kernel issue affecting 2.6 kernels before 2.6.15. A local user could trigger sysctl handling of an overly long string, causing memory corruption in user memory and possibly denial of service. The CVE itself notes uncertainty about whether this is exploitable without a user-assisted or setuid scenario. Exposure is mainly legacy Linux systems running 2.6 kernels before 2.6.15, or distribution kernels that lacked the 2006 vendor fixes. Modern supported Linux kernels are unlikely to be exposed, but embedded, appliance, or long-retired systems should be checked. Treat this as a legacy exposure cleanup item, not an emergency, unless business-critical systems still run affected 2.6-era kernels. Priority should rise for shared servers, appliances, or environments where local users can execute code. Mitigation focus: Inventory systems for Linux kernel 2.6 versions before 2.6.15.; Apply the relevant Debian, Mandriva, Ubuntu, or vendor kernel security updates.; Upgrade unsupported legacy kernels to a supported maintained kernel line..
