SUSE CVE-2026-89957

In the Linux kernel, the following vulnerability has been resolved: s390/vfio-ap: Fix hot-unplug skipped when last AP adapter or domain removed The vfioapmdevhotunplugcfg function uses the return value of bitmapandnot to determine whether the guest APCB needs to be updated. However, bitmapandnot...

SUSE CVE-2026-89960

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-2026-89958

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. ...
