AI-suggested

Until a fix is available, avoid performing recursive copies (-R) on device nodes using the affected versions of rust-coreutils.

Description

A vulnerability in the cp utility of rust-coreutils causes recursive copies (-R) to mishandle character and block device nodes by copying their contents as regular files instead of preserving device semantics. This can lead to denial of service conditions such as disk exhaustion or process hangs when interacting with device nodes like /dev/null.
