Subject: [PATCH 0/2] PCI/MSI: Hardening fixes
Date: Thu, 19 Jan 2023 19:06:31 +0200	[thread overview]
Message-ID: <20230119170633.40944-1-alexander.shishkin@linux.intel.com> (raw)

Hi,

Here are 2 hardening fixes around MSIX table size/offset handling,
aiming to prevent a malicious device or VMM from triggering bugs by
supplying bogus values.

Alexander Shishkin (2):
  PCI/MSI: Cache the MSIX table size
  PCI/MSI: Validate device supplied MSI table offset and size
