Description
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: imx-sdma: Fix a possible memory leak in sdma_transfer_init
If the function sdma_load_context() fails, the sdma_desc will be
freed, but the allocated desc->bd is forgot to be freed.
We already met the sdma_load_context() failure case and the log as
below:
[ 450.699064] imx-sdma 30bd0000.dma-controller: Timeout waiting for CH0 ready
...
In this case, the desc->bd will not be freed without this change.
Affected configurations
• linux linux kernel (< 4.19.272)
• linux linux kernel (>= 4.20 < 5.4.231)
• linux linux kernel (>= 5.5 < 5.10.167)
