Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> hfsplus: ensure sb-&gt;s_fs_info is always cleaned up<br /> <br /> When hfsplus was converted to the new mount api a bug was introduced by<br /> changing the allocation pattern of sb-&gt;s_fs_info. If setup_bdev_super()<br /> fails after a new superblock has been allocated by sget_fc(), but before<br /> hfsplus_fill_super() takes ownership of the filesystem-specific s_fs_info<br /> data it was leaked.<br /> <br /> Fix this by freeing sb-&gt;s_fs_info in hfsplus_kill_super().
