The existing check only proves:\n`dx > 0 => xsize  xsize >= INT_MIN - dx`\nTaking `dx = -32768` and repeating it 65,537 times, the mathematical sum is `-2,147,516,416`, which is less than `INT_MIN = -2,147,483,648`. On the 65,537th addition, the operation `-2147483648 + -32768` is performed, resulting in **C signed overflow undefined behavior**.\n\n### PoC\n```python\n\"\"\"Minimal public-API reproducer for the Pillow 12.3.0 textwidth underflow.\n\nRun with an ordinary Pillow 12.3.0 build to observe the wrapped width, ","public_affected_ranges":["< 13.0.0"]}],"null_published_at":"2026-10-31T22:27:12.379Z","source_updated_at":"2026-10-22T16:01:15.000Z","source_disclosed_at":"2026-10-22T16:01:14.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T22:07:30.906Z"}],"next_cursor":null,"snapshot_revision":"42594"}
