CVE-2026-4897: Allocation of Resources Without Limits or Throttling in Red Hat Red Hat Enterprise Linux 10
A flaw was found in polkit. A local user can exploit this by providing a specially crafted, excessively long input to the `polkit-agent-helper-1` setuid binary via standard input (stdin). This unbounded input can lead to an out-of-memory (OOM) condition, resulting in a Denial of Service (DoS) for the system.
