Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A missing runtime PM reference exists in the ccs mode store() function. This function calls xe gt reset(), which internally invokes xe pm runtime get noresume(). Because xe pm runtime get noresume() requires the caller to already hold an outer runtime PM reference, its invocation without one triggers a warning.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
