Subject: [PATCH 0/2] cxl: Fix endpoint access issues with CXL MCE notifier handler
Date: Mon, 15 Jun 2026 17:40:05 -0700 [thread overview]
Message-ID: <20260616004007.4186004-1-dave.jiang@intel.com> (raw)
Fix the issues reported by Flavien to the Linux security mailing list.
First patch addresses accessing possible invalid pointers for cxlmd and
cxmd->endpoint.
The second patch adddresses the endpoint lifetime that is shorter than
mds and needs appropriate guardrails to access.
Dave Jiang (2):
cxl/mce: Validate memdev and endpoint before dereference in
cxl_handle_mce()
cxl/mce: Serialize the MCE handler against endpoint teardown
