Description OSIDB Bzimport 2024-11-19 18:01:29 UTC 
In the Linux kernel, the following vulnerability has been resolved:

firmware: qcom: scm: fix a NULL-pointer dereference

Some SCM calls can be invoked with __scm being NULL (the driver may not
have been and will not be probed as there's no SCM entry in device-tree).
Make sure we don't dereference a NULL pointer.
