✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Build environments should avoid running LTO-enabled linking (ld with plugin support) against untrusted or externally-supplied object and archive files. The linker is a build-time tool, not present in production runtimes, so the realistic exposure is to CI/CD pipelines and developer workstations that build from untrusted or externally-contributed sources (supply-chain style attack). Standard hardening measures (ASLR, stack protector, FORTIFY_SOURCE, PIE) substantially reduce the likelihood of arbitrary code execution via heap manipulation, limiting the more realistic impact to a linker crash (denial of service).
