Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
RDMA/mlx4: Fix mis-use of RCU in mlx4_srq_event()<br />
<br />
Sashiko points out the radix_tree itself is RCU safe, but nothing ever<br />
frees the mlx4_srq struct with RCU, and it isn&#39;t even accessed within the<br />
RCU critical section. It also will crash if an event is delivered before<br />
the srq object is finished initializing.<br />
<br />
Use the spinlock since it isn&#39;t easy to make RCU work, use<br />
refcount_inc_not_zero() to protect against partially initialized objects,<br />
and order the refcount_set() to be after the srq is fully initialized.
