CVE-2026-43206 is an out-of-bounds write vulnerability in the Linux kernel AMD KFD DRM component. The kfd_event_page_set() function uses memset to write KFD_SIGNAL_EVENT_LIMIT * 8 bytes without validating the supplied buffer-size parameter. An unprivileged userspace caller can supply an undersized buffer, causing a write beyond its bounds into kernel memory and potentially enabling privilege escalation.
