From 5678f3b366c28c6828d32bd758fda4d6b965aebf Mon Sep 17 00:00:00 2001 From: Michael Tuexen Date: Thu, 9 May 2024 00:17:13 +0200 Subject: [PATCH] sctp: don't provide uninitialized memory to process_chunk_drop() Right now, the code in process_chunk_drop() does not look the the corresponding fields. Therefore, no functional change intended.
