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-2026-98179

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...
