Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Release m2m_ctx after Instance Removed from List Possible use after free if IRQ thread manages to obtain spinlock between m2m_ctx release and wave5_release function removing stream instance from list of active instances. The IRQ thread looks for the m2m_ctx which is freed so null pointer dereference occurs.
