In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()
The kfd_event_page_set() function writes KFD_SIGNAL_EVENT_LIMIT * 8
bytes via memset without checking the buffer size parameter. This allows
unprivileged userspace to trigger an out-of bounds kernel memory write
by passing a small buffer, leading to potential privilege
escalation.
