Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
RDMA/irdma: Cap MSIX used to online CPUs + 1<br />
<br />
The irdma driver can use a maximum number of msix vectors equal<br />
to num_online_cpus() + 1 and the kernel warning stack below is shown<br />
if that number is exceeded.<br />
<br />
The kernel throws a warning as the driver tries to update the affinity<br />
hint with a CPU mask greater than the max CPU IDs. Fix this by capping<br />
the MSIX vectors to num_online_cpus() + 1.<br />
<br />
