CVE-2022-50634

Estado: AplazadaSin puntuar—

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

power: supply: cw2015: Fix potential null-ptr-deref in cw_bat_probe()

cw_bat_probe() calls create_singlethread_workqueue() and not checked the ret value, which may return NULL. And a null-ptr-deref may happen:

Check the ret value and return -ENOMEM if it is NULL.
