From fbe2dc6a9c7318f7263f5e4d50f6272b931c5756 Mon Sep 17 00:00:00 2001 From: Sang-Heon Jeon Date: Tue, 23 Sep 2025 17:16:45 +0900 Subject: [PATCH] smb: client: fix wrong index reference in smb2_compound_op() In smb2_compound_op(), the loop that processes each command's response uses wrong indices when accessing response bufferes. This incorrect indexing leads to improper handling of command results. Also, if incorrectly computed index is greather than or equal to MAX_COMPOUND, it can cause out-of-bounds accesses.
