Summary
In the Linux kernel, the following vulnerability has been resolved:
soc: mediatek: svs: Fix memory leak in svs_enable_debug_write()
In svs_enable_debug_write(), the buf allocated by memdup_user_nul() is leaked if kstrtoint() fails.
Fix this by using __free(kfree) to automatically free buf, eliminating the need for explicit kfree() calls and preventing leaks.
[Angelo: Added missing cleanup.h inclusion]
