In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix control domain removal in vfioapmdevcfgremove The vfioapconfigremove function uses the bitmapandnot function to clear bits from the matrixmdev-matrix.adm bitmap specifies the control domains assigned to the mdev...
DEBIAN-CVE-2026-89955
In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix NULL deref in statusshow during queue probe When vfioapmdevprobequeue creates the sysfs attribute group, the queue's driver data has not yet been set. A concurrent read of the 'status' attribute can therefore ca...
DEBIAN-CVE-2026-89956
In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix missing lock required to access list of apmatrixmdev objects In order to traverse or add/remove apmatrixmdev objects in the matrixdev-mdevlist, the matrixdev-guestslock mutex must be held. There are two function...

CVE-2026-89960
CVE-2026-89960 is a use-after-free in the Linux kernel's s390 vfio-ap (Protected Crypto Accelerator) subsystem. In vfio_ap_mdev_set_kvm(), the kvm->arch.crypto.pqap_hook pointer is set before checking for a conflicting mdev assignment. If another mdev already owns the KVM instance, the functio...
CVE-2026-89960 s390/vfio-ap: fix stale pqap_hook pointer on error in vfio_ap_mdev_set_kvm()

CVE-2026-89959
CVE-2026-89959 is a Linux kernel vulnerability in the s390/vfio-ap subsystem. The vfio_ap_config_remove function incorrectly used bitmap_andnot instead of bitmap_and when clearing bits from the matrix_mdev->matrix.adm bitmap (which tracks control domains assigned to a mediated device). This pr...

In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix dereference matrixmdev-kvm without checking for NULL The apdriver structure has two fields which are function pointers to callbacks: .onconfigchanged: called at the start of the AP bus scan function to notify th...
CVE-2026-89957
CVE-2026-89957 affects the Linux kernel s390 vfio-ap driver. In vfio_ap_mdev_hot_unplug_cfg(), the return value of bitmap_andnot() is used to decide whether the guest APCB needs updating. When the last AP adapter or domain assigned to an mdev is removed, the resulting empty bitmap causes bitmap_a...

CVE-2026-89955
A NULL pointer dereference vulnerability exists in the Linux kernel's s390/vfio-ap module. The race occurs when vfio_ap_mdev_probe_queue() creates the sysfs attribute group before the queue's driver data is set; a concurrent read of the status attribute then retrieves NULL via dev_get_drvdata() a...
CVE-2026-89956
CVE-2026-89956 affects the s390/vfio-ap subsystem of the Linux kernel. The root cause is a missing matrix_dev->guests_lock mutex when traversing or modifying the mdev_list of ap_matrix_mdev objects. Two functions are affected: vfio_ap_mdev_probe , which added objects to the list using the wron...
