+Subject: [PATCH] Validate large filter sizes when initializing RankFilter
+ (#9695)
+
+CVE: CVE-2026-59197
+Upstream-Status: Backport [https://github.com/python-pillow/Pillow/commit/cce3bdb867c77a3420261ed1bfdb6b0787ec8fc1]
+
+Backport Changes:
+- Adapted the ImagingExpand check to Pillow 12.2.0's two-margin API.
+  It checks the larger margin and guards against zero before division;
+  the regression test passes both margins.
+
+(cherry picked from commit cce3bdb867c77a3420261ed1bfdb6b0787ec8fc1)
