CVE-2026-74447

In the Linux kernel (drm/amdkfd), a uint32_t overflow in EOP ring buffer size alignment was fixed. The issue occurred because eop_ring_buffer_size (u32) is aligned with PAGE_SIZE in kfd_queue_acquire_buffers() using 32‑bit arithmetic, allowing a user size like 0xFFFFF001 to wrap to 0 and bypass t...
