Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
RDMA: hfi1: fix possible divide-by-zero in find_hw_thread_mask()<br />
<br />
The function divides number of online CPUs by num_core_siblings, and<br />
later checks the divider by zero. This implies a possibility to get<br />
and divide-by-zero runtime error. Fix it by moving the check prior to<br />
division. This also helps to save one indentation level.
