Hmm. git show be040d7df68a8cbb244aaabc37832984dafcbf55
+Exim version 4.98.2
+-------------------
+
+This is a security release, addressing CVE-2025-30232
+
+JH/01 Fix use-after-free notified by Trend Micro (ref: ZDI-CAN-26250).
+      Null out debug_pretrigger_buf pointer before freeing the buffer;
+      the use of this buffer by the storage management checks the pointer
+      for non-null before using it.
+

... so I would not advise anyone that 4.98.1 is safe,
even if it is not vulnerable to CVE-2025-67896
