In the Linux kernel, the following vulnerability has been resolved:
genirq/irq_sim: Initialize work context pointers properly
Initialize `ops` member's pointers properly by using kzalloc() instead of
kmalloc() when allocating the simulation work context. Otherwise the
pointers contain random content leading to invalid dereferencing.
