Title
ASoC: amd/sdw_utils: avoid NULL deref when devm_kasprintf() fails
Summary
In the Linux kernel, the following vulnerability has been resolved: ASoC: amd/sdw_utils: avoid NULL deref when devm_kasprintf() fails devm_kasprintf() may return NULL on memory allocation failure, but the debug message prints cpus->dai_name before checking it. Move the dev_dbg() call after the NULL check to prevent potential NULL pointer dereference.
Severity
