CVE-2022-50169
In the Linux kernel, the following vulnerability has been resolved: wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi() The simple_write_to_buffer() function will succeed if even a single byte is initialized.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi() The simple_write_to_buffer() function will succeed if even a single byte is initialized. However, we need to initialize the whole buffer to prevent information leaks. Just use memdup_user().
