Subject: [PATCH 0/2] KVM: s390: Limit adapter indicator access to page
Date: Tue, 17 Feb 2026 09:54:21 +0100 [thread overview]
Message-ID: <20260217090230.8116-1-frankja@linux.ibm.com> (raw)
We currently check the address of the indicator fields but not the sum
of address and offset. This patch remedies that problem and limits the
address + offset combination to a single page.
The selftest is very rudimentary but it's a start.
