CVE-2023-52663 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ASoC: SOF: amd: Fix memory leak in amd_sof_acp_probe()

Driver uses kasprintf() to initialize fw_codedata_bin members of struct acp_dev_data but kfree() is never called to deallocate the memory which results in a memory leak.

Fix the issue by switching to devm_kasprintf(). Additionally ensure the allocation was successful by checking the pointer validity.
