https://notcve.org/view.php?id=CVE-2024-27055
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 ...

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: fix double module refcount decrement Once the discipline is associated with the device, deleting the device takes care of decrementing the module's refcount. Doing it manually on this error path causes refcount to artificially decrease on each error while it should just stay the same. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: s390/dasd: corrige la disminución del doble recuento del módulo Una vez que la disciplina está asociada con el dispositivo, eliminar el dispositivo se encarga de disminuir el recuento del módulo.
