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.

No CVSS v4.0

Attack Vector Local

Attack Complexity Low

Privileges Required Low

Scope Unchanged

Confidentiality Impact None

Integrity Impact None

Availability Impact High

User Interaction None

No CVSS v3.0

No CVSS v2

This CVE is not in the KEV list.

The EPSS score is 0.00051.

Exploitation none

Automatable no

Technical Impact partial
