Mitigation checklist
- To mitigate this vulnerability, if HPLIP functionality is not required, consider removing the `hplip` package. This action will remove support for HP printers and may impact printing capabilities. Use the system's package manager to perform this operation. For example, on Red Hat Enterprise Linux, execute `sudo dnf remove hplip`.
