CVE-2024-56580

Estado: ModificadaMedia (5.5)—

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

media: qcom: camss: fix error path on configuration of power domains

There is a chance to meet runtime issues during configuration of CAMSS power domains, because on the error path dev_pm_domain_detach() is unexpectedly called with NULL or error pointer.

One of the simplest ways to reproduce the problem is to probe CAMSS driver before registration of CAMSS power domains, for instance if a platform CAMCC driver is simply not built.

Warning backtrace example:
