Fedora 42 Rust-Resctl-Bench Important Permissions Issue CVE-2026-33056

Dist Fedora Esm H88
Critical update for Fedora 42's rust-resctl-bench addresses CVE-2026-33056 with essential fixes for permissions.
Rebuilt with rust-tar 0.4.45 for CVE-2026-33056

Summary

resctl-bench is a collection of whole-system benchmarks to evaluate resource

control and hardware behaviors using realistic simulated workloads.

Comprehensive resource control involves the whole system. Furthermore, testing

resource control end-to-end requires scenarios involving realistic workloads

and monitoring their interactions. The combination makes benchmarking resource

control challenging and error-prone. It's easy to slip up on a configuration

and testing with real workloads can be tedious and unreliable.

resctl-bench encapsulates the whole process so that resource control benchmarks

can be performed easily and reliably. It verifies and updates system

configurations, reproduces resource contention scenarios with a realistic

latency-sensitive workload simulator and other secondary workloads, analyzes

the resulting system and workload behaviors, and generates easily

understandable reports.
