CVE-2005-3271: Exec in Linux kernel 2.6 does not properly clear posix-timers in multi-threaded environments, which results...

Security readout for executives and security teams

This is an old Linux kernel denial-of-service issue. On affected Linux 2.6 systems, local users could trigger a POSIX timer resource leak and collectively exhaust timer quotas, disrupting service. It is most relevant to legacy, multi-user systems that still run vulnerable vendor kernels. Exposure is likely limited to legacy Linux 2.6 deployments, especially shared shell, hosting, lab, appliance, or multi-user systems. Modern supported kernels are unlikely to be affected, but the source bundle does not enumerate exact fixed versions. Treat as a legacy exposure cleanup item unless vulnerable multi-user Linux 2.6 systems remain in production. If they do, schedule remediation promptly because local users could disrupt availability. Mitigation focus: Inventory systems still running Linux 2.6 kernels.; Apply the relevant vendor kernel security update where available.; Upgrade unsupported legacy kernels to a maintained distribution release..
