CVE-2026-89810

CVE-2026-89810 affects the Linux kernel in the drm/amdkfd subsystem (AMD KFD driver). The root cause lies in the svm_migrate_copy_to_ram error path: when page migration from device to system RAM fails, the driver incorrectly used the DMA address (for adev) instead of the page PFN to release and u...
