A flaw was found in HPLIP (HP Linux Imaging and Printing Software). This vulnerability, an incomplete fix for CVE-2026-8631, may allow a remote attacker to escalate privileges or achieve arbitrary code execution. This can occur through an integer overflow in the hpcups processing path when handling specially crafted print data.
To mitigate this vulnerability, consider restricting access to the printing services to trusted users and networks. If HPLIP is not required, removing the hplip package can eliminate the exposure. Note that removing hplip may affect printing functionality.
