From eb8db421ce83f4acf3ca51e642120f42adea3a7b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Wei=C3=9Fschuh?= Date: Mon, 17 Feb 2025 08:37:58 +0100 Subject: [PATCH] riscv: mm: Don't use %pK through printk MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Restricted pointers ("%pK") are not meant to be used through printk(). It can unintentionally expose security sensitive, raw pointer values. Use regular pointer formatting instead.
