- dmaengine: qcom-adm: fix wrong sizeof config in slave_config
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: qcom-adm: fix wrong sizeof config in slave_config
Fix broken slaveconfig function that uncorrectly compare the peripheralsize with the size of the config pointer instead of the size of the config struct. This cause the crci value to be ignored and cause a kernel panic on any slave that use adm driver.
To fix this, compare to the size of the struct and NOT the size of the pointer.
