Subject: [PATCH AUTOSEL 5.10 01/11] KVM: s390: Don't use %pK through tracepoints
Date: Mon, 14 Apr 2025 09:31:48 -0400 [thread overview]
Message-ID: <20250414133158.681045-1-sashal@kernel.org> (raw)
From: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
[ Upstream commit 6c9567e0850be2f0f94ab64fa6512413fd1a1eb1 ]
Restricted pointers ("%pK") are not meant to be used through TP_format().
It can unintentionally expose security sensitive, raw pointer values.
Use regular pointer formatting instead.
