From 8d139e3635c86e2c97c78d55538ce0b00b6d9986 Mon Sep 17 00:00:00 2001 From: Hongling Zeng Date: Mon, 24 Aug 2026 13:41:15 +0800 Subject: [PATCH] ntfs: fix incorrect MFT record pointer passed to ntfs_attr_record_resize ntfs_new_attr_flags() passes the wrong MFT record to ntfs_attr_record_resize(). When the attribute is in an extent record, ctx->mrec points to the extent but the function receives the base record pointer m, causing incorrect size calculations in memmove. Fix by passing ctx->mrec (the actual MFT record containing the attribute) instead of m (the base MFT record) to ntfs_attr_record_resize().
