CISA-ADP AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H

CISA-ADP CWE-400

In the Linux kernel, the following vulnerability has been resolved:

enetc: Fix illegal access when reading affinity_hint

irq_set_affinity_hit() stores a reference to the cpumask_t
parameter in the irq descriptor, and that reference can be
accessed later from irq_affinity_hint_proc_show(). Since
the cpu_mask parameter passed to irq_set_affinity_hit() has
only temporary storage (it's on the stack memory), later
accesses to it are illegal. Thus reads from the corresponding
procfs affinity_hint fi
