What it is

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.
