Subject: [PATCH v1 0/2] Address UAF in sunrpc cache show callbacks
Date: Thu, 19 Feb 2026 16:50:15 -0500 [thread overview]
Message-ID: <20260219215017.1769-1-cel@kernel.org> (raw)
From: Chuck Lever <chuck.lever@oracle.com>
Attempt to address three crashes reported here:
https://lore.kernel.org/linux-nfs/dcd371d3a95815a84ba7de52cef447b8@linux.ibm.com/
These are compile-tested and regression-tested, but as I do not have
a PowerPC system handy, I will need someone who has one to test
whether they actually address the crashes.
