Sudo-rs panics when executing a shell script without execute permission

1

My Ubuntu Budgie install was updated to Ubuntu 25.10 last week which replaced sudo with the rust sudo-rs version.

Today I was executing a bash script with sudo and forgot to grant the script execute permission. Not a big problem however the response from sudo-rs was a panic, rather than a gracefully handled error message.

I retested with a very simple script and the panic is 100% reproducible.

Is this the same bug as: Fix a panic when exec fails with use_pty enabled by bjorn3 · Pull Request #1298 · trifectatechfoundation/sudo-rs · GitHub

sudo ./test

#!/bin/bash
sudo apt update

thread ‘main’ panicked at src/exec/use_pty/monitor.rs:283:45:
internal error: entered unreachable code
note: run with RUST_BACKTRACE=1 environment variable to display a backtrace
sudo-rs: cannot execute ‘/home/REDACTED/test’: Permission denied (os error 13)
