Subject: [PATCH 0/2] KVM: s390: Don't use %pK through debug printing or tracepoints
Date: Mon, 17 Feb 2025 14:13:55 +0100 [thread overview]
Message-ID: <20250217-restricted-pointers-s390-v1-0-0e4ace75d8aa@linutronix.de> (raw)
Restricted pointers ("%pK") are only meant to be used when directly
printing to a file from task context.
Otherwise it can unintentionally expose security sensitive, raw pointer values.
Use regular pointer formatting instead.
