CVE-2022-50169: wifi: wil6210: debugfs: fix info leak in wil_write_file_wmi()
Noroxi assessment
Priority: Monitor (action score 28/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.26% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 05ceda14ef7c73104e709c414c3680d8a59f51d4, 074e865b37da55aa87baa16d68b96896f85f8adb, 4615458db7793fadc6d546ac3564b36819e77a22.
Low priority for now. Upgrade to Linux Linux 05ceda14ef7c73104e709c414c3680d8a59f51d4, 074e865b37da55aa87baa16d68b96896f85f8adb, 4615458db7793fadc6d546ac3564b36819e77a22 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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().
