Subject: [PATCH 0/9] s390x: even more hardening fixes
Date: Wed, 16 Sep 2026 22:32:32 +0200	[thread overview]
Message-ID: <20260916203242.2509787-1-farman@linux.ibm.com> (raw)

Hi Christian, Matt,

Here's a small pile of additional hardening fixes for consideration.

Took a stab at what should be cc'd to stable vs what shouldn't be,
but open to other opinions.

Eric Farman (9):
  virtio-ccw: Limit ISC to MAX_ISC
  virtio-ccw: Do not overwrite existing indicators
  virtio-ccw: Fix rc check in read configuration path
  vfio/ap: Clear error object pointer after non-fatal errors
  vfio/ccw: Clear error object pointer after non-fatal errors
  hw/intc/s390x: Fix payload to KVM_HAS_DEVICE_ATTR ioctl
  hw/intc/s390x: Fix check after g_try_realloc
  s390x/css: Expand check against no-data-count CCWs
  s390x/sclp: Reject short headers in PV case
