+Subject: [PATCH] t38: Allocate forced defragmented memory in correct scope
+
+Fragment data can't be allocated in pinfo->pool scope, as it
+outlives the frame. Set it to be freed when the associated tvb
+is freed, as done in the main reassemble.c code.
+
+Fix #19695
+
+CVE: CVE-2024-2955
+Upstream-Status: Backport [https://gitlab.com/wireshark/wireshark/-/commit/6fd3af5e999c71df67c2cdcefb96d0dc4afa5341]
