Memory Leak Vulnerability in Linux Kernel Affecting Device Registration

CVE-2022-50547

What is CVE-2022-50547?

A memory leak exists in the Linux kernel's solo6x10 driver, specifically during the device registration process. If the function device_register() fails while initializing the solo_sysfs_init() function, the allocated name must be released using put_device(). Failing to do so could lead to unnecessary memory consumption, ultimately impacting system performance. The fix addresses this issue by ensuring that resources are properly managed when an error occurs, thereby enhancing the stability and security of the Linux kernel.
