Rustam Kovhaev cd12577b52 ntfs: add check for mft record size in superblock ... [ Upstream commit 4f8c94022f0bc3babd0a124c0a7dcdd7547bd94e ] Number of bytes allocated for mft record should be equal to the mft record size stored in ntfs superblock as reported by syzbot, userspace might trigger out-of-bounds read by dereferencing ctx->attr in ntfs_attr_find() Reported-by: syzbot+aed06913f36eff9b544e@syzkaller.appspotmail.com Signed-off-by: Rustam Kovhaev <rkovhaev@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Tested-by: syzbot+aed06913f36eff9b544e@syzkaller.appspotmail.com Acked-by: Anton Altaparmakov <anton@tuxera.com> Link: https://syzkaller.appspot.com/bug?extid=aed06913f36eff9b544e Link: https://lkml.kernel.org/r/20200824022804.226242-1-rkovhaev@gmail.com Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2021-03-16 16:39:16 +08:00
