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_{code,data}_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.

Affected products

• Linux kernel: from 6.6 before 6.6.23; from 6.7 before 6.7.11; from 6.8 before 6.8.2 — fixed in 6.6.23, 6.7.11, 6.8.2

How to fix
