What is the issue?

Description

A runtime panic occurs when running ./ollama list if a model has a digest (ID) shorter than 12 characters. This happens because the code unconditionally attempts to slice the digest string using [:12] without checking its actual length.

Steps to Reproduce

Introduce a model with a short digest (e.g., via a malformed manifest or manual code injection).

Run ./ollama list.

The application crashes with: panic: runtime error: slice bounds out of range [:12].

Observed Behavior

The program terminates abruptly:

panic: runtime error: slice bounds out of range [:12] with length 3
goroutine 1 [running]:
github.com/ollama/ollama/cmd.ListHandler(...)
/home/turko/ollama/cmd/cmd.go:835

Expected Behavior

The command should list the models safely, showing the full digest if it's short, or a placeholder if it's empty, without crashing the CLI.

Proposed Fix

Implement a bounds check before slicing the digest string in cmd/cmd.go:

displayID := m.Digest
if len(displayID) > 12 {
displayID = displayID[:12]
}

@driftttttt commented on GitHub (Feb 14, 2026):

checked the source, it indeed panics at line 835 in cmd/cmd.go. bounds check is missing there. simple if len > 12 should fix it.
