CVE-2026-68103

The CVE-2026-68103 issue affects the Linux kernel drm/amdgpu component. The root cause is the use of xa_store_irq() when creating a user-queue doorbell mapping, which can allow a later queue with the same BO and offset to overwrite an existing queue and doorbell mapping. This can misroute fence I...

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...
