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