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.

kernel: drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()
A flaw was found in the Linux kernel's drm/amdkfd component. An unprivileged local user can exploit an out-of-bounds write vulnerability in the kfd_event_page_set() function. This occurs because the function writes data without properly validating the buffer size, allowing a small buffer to trigger a write beyond its allocated memory. Successful exploitation of this flaw could lead to potential privilege escalation.
