Official description

In the Linux kernel, the following vulnerability has been resolved: dmaengine: qcom-adm: fix wrong sizeof config in slave_config Fix broken slave_config function that uncorrectly compare the peripheral_size with the size of the config pointer instead of the size of the config struct.
