JLSEC-2026-922 ImageMagick has Undefined Behavior (function-type-mismatch) in CloneSplayTree

Summary - Target: ImageMagick commit ecc9a5eb456747374bae8e07038ba10b3d8821b3 - Type: Undefined Behavior function-type-mismatch in splay tree cloning callback - Impact: Deterministic abort under UBSan DoS in sanitizer builds. No crash in a non-sanitized build; likely low security impact. - Trigge...
