Niels Provos Systrace 1.6f and earlier on the x86_64 Linux platform allows local users to bypass intended access restrictions by making a 32-bit syscall with a syscall number that corresponds to a policy-compliant 64-bit syscall, related to race conditions that occur in monitoring 64-bit processes.

Security readout for executives and security teams

This CVE affects Systrace 1.6f and earlier on x86_64 Linux. A local user could bypass Systrace access restrictions by using syscall numbering behavior that confuses 32-bit and 64-bit monitoring. Business urgency depends on whether Systrace protects untrusted local users or workloads. Exposure is likely limited to x86_64 Linux systems running Niels Provos Systrace 1.6f or earlier, especially where Systrace enforces restrictions for local users, shared systems, or sandboxed processes. Treat as a targeted local isolation risk, not a broad internet-facing emergency. Prioritize shared Linux servers, research environments, and systems depending on Systrace for sandbox boundaries. Mitigation focus: Inventory Systrace installations and versions on x86_64 Linux systems.; Check Systrace project or distribution guidance for fixed versions or advisories.; Do not rely on vulnerable Systrace alone for untrusted local-user isolation..
