Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
shmem: use ramfs_kill_sb() for kill_sb method of ramfs-based tmpfs<br />
<br />
As the ramfs-based tmpfs uses ramfs_init_fs_context() for the<br />
init_fs_context method, which allocates fc->s_fs_info, use ramfs_kill_sb()<br />
to free it and avoid a memory leak.
