CVE-2022-49104

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

staging: vchiq_core: handle NULL result of find_service_by_handle

In case of an invalid handle the function find_servive_by_handle returns NULL. So take care of this and avoid a NULL pointer dereference.

This vulnerability is rated as Moderate impact because an authenticated local user could cause a kernel crash resulting in a denial of service, while remote exploitation and confidentiality or integrity compromise are not possible. The flaw exists in the staging driver for Broadcom VideoCore services, which is not built or enabled in Red Hat Enterprise Linux kernels. Consequently, standard Red Hat enterprise installations do not ship the affected driver and remain unaffected.
