CVE-2026-98179

A vulnerability in the Linux kernel 's drm/amdgpu driver causes a memory leak during device removal. Specifically, the amdgpu_pci_remove() function calls drm_dev_unplug() before fini_sw(), resulting in drm_dev_enter() being false. This causes the iounmap() call, which is guarded by that check, to...

EUVD-2026-93107

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix rmmio iounmap skipped on device removal amdgpupciremove calls drmdevunplug before finisw, so drmdeventer is already false there and the iounmap guarded by it is skipped. This .remove path runs on both hot-unplug a...

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...
