✅ Remediation

Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 Workaround: To mitigate this issue, applications using the `Expr` library should ensure that evaluation environments do not contain cyclic references. Additionally, externally supplied data structures must be validated or sanitized before being passed to `Expr` for evaluation. As a last-resort defensive measure, expression evaluation can be wrapped with panic recovery to prevent a full process crash.
