In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: fix stale pqaphook pointer on error in vfioapmdevsetkvm In vfioapmdevsetkvm, kvm-arch.crypto.pqaphook is set to &matrixmdev-pqaphook before the update locks are acquired and the mdev list is checked for a conflictin...
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-2026-89958 s390/vfio-ap: Fix dereference matrix_mdev->kvm without checking for NULL
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-2026-89959 s390/vfio-ap: Fix control domain removal in vfio_ap_mdev_cfg_remove
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...
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...
CVE-2026-89958
This vulnerability affects the Linux kernel 's s390/vfio-ap driver. The root cause is a NULL pointer dereference : the vfio_ap_on_cfg_changed and vfio_ap_on_scan_complete callback functions acquire the matrix_mdev->kvm->lock mutex without first checking whether matrix_mdev->kvm is NULL. ...
