AI-suggested
A fix has been implemented to address this memory leak by adding the missing kfree call in acp6x_pdm_dma_close(). Users should apply the updated linux-hwe-edge kernel versions that include this patch to remediate the issue.
Description
A memory leak vulnerability in the Linux kernel's ASoC AMD YC driver was fixed. The function acp6x_pdm_dma_close() failed to free a buffer allocated in acp6x_pdm_dma_open(), causing a memory leak. This issue affects specific versions of the linux-hwe-edge kernel.
