Summary
In the Linux kernel, the following vulnerability has been resolved: workqueue: Don't call cpumask_test_cpu() with -1 CPU in wq_update_node_max_active() For wq_update_node_max_active(), @off_cpu of -1 indicates that no CPU is going down. The function was incorrectly calling cpumask_test_cpu() with -1 CPU leading to oopses like the following on some archs: Unable to handle kernel paging request at virtual address ffff0002100296e0 .. pc : wq_update_node_max_active+0x50/0x1fc lr : wq_update_node_max_active+0x1f0/0x1fc ...
