Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A fix has been applied to the Linux kernel to address an information leak issue in the wil write file wmi() function. The problem occurred because the simple write to buffer() function considered the operation successful even if only a single byte was initialized, which could lead to information leaks. To resolve this, the memdup user() function is used to ensure the entire buffer is initialized.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
