Description

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.
