CVE-2020-29534

CVE-2020-29534 affects the Linux kernel prior to 5.9.3. The io_uring subsystem takes a non-refcounted reference to the submitting process’ files_struct, which can lead to incorrect optimization of unshare_fd() during execve(), as CID-0f2122045b94 describes. This is a local vulnerability with pote...
