✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: Applications can mitigate this issue by avoiding calls to erase_if() on __gnu_pbds::priority_queue containers that use the binary_heap_tag backend. Where predicate-based removal is required, use an alternative container or a different heap backend in application code. Apart from applying a fixed package when one becomes available, no other mitigation is currently available.
