Summary
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.
