Subject: [PATCH 6.1 15/71] fs/ntfs3: Validate BOOT record_size
Date: Mon, 2 Jan 2023 12:21:40 +0100 [thread overview]
Message-ID: <20230102110552.085997529@linuxfoundation.org> (raw)
In-Reply-To: <20230102110551.509937186@linuxfoundation.org>
From: edward lo <edward.lo@ambergroup.io>
[ Upstream commit 0b66046266690454dc04e6307bcff4a5605b42a1 ]
When the NTFS BOOT record_size field < 0, it represents a
shift value. However, there is no sanity check on the shift result
and the sbi->record_bits calculation through blksize_bits() assumes
the size always > 256, which could lead to NPD while mounting a
malformed NTFS image.
