Niels Provos Systrace before 1.6f on the x86_64 Linux platform allows local users to bypass intended access restrictions by making a 64-bit syscall with a syscall number that corresponds to a policy-compliant 32-bit syscall.

Security readout for executives and security teams

This issue affects old Systrace deployments on x86_64 Linux. A local user could bypass Systrace’s intended access restrictions because syscall filtering could misinterpret policy between 32-bit and 64-bit syscall numbering. Business urgency is mainly for legacy systems that still rely on Systrace as a security boundary. Exposure is likely limited to legacy x86_64 Linux systems running Niels Provos Systrace before 1.6f, especially where Systrace policies are used to constrain local users or sandbox processes. Prioritize as a legacy exposure review, not an internet-wide emergency. Escalate if Systrace protects sensitive workloads or multi-user systems where local users are not fully trusted. Mitigation focus: Upgrade Systrace to 1.6f or later where still deployed.; Check upstream or distribution guidance for supported remediation details.; Do not treat vulnerable Systrace filtering as a sole security boundary..
