CVE-2026-68102 drm/amdgpu: fix aperture mapping leak

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix aperture mapping leak amdgpupciremove calls drmdevunplug before invoking the driver fini routines. This causes drmdeventer in amdgputtmfini to always return false, so iounmapaperbasekaddr never runs on normal driv...

CVE-2026-68102

The CVE-2026-68102 entry documents a kernel fix in drm/amdgpu to prevent an aperture mapping leak during driver unload. The root cause was amdgpu_pci_remove() calling drm_dev_unplug() before driver fini, which caused drm_dev_enter() in amdgpu_ttm_fini() to fail and left iounmap(aper_base_kaddr) a...
