A common code pattern for double free (and other issues) is incorrect life-time management along error paths.Sometimes this will result in use-after-frees but in this case its a double free…

A pretty classic command injection vulnerability but in ClamAV.Often seen (in my experience) running on mail-servers to scan incoming email attachments…
The Mediatek wlan driver on Android has several files exposed under the /proc
