In the ea_get function in fs/jfs/xattr.c in the Linux kernel through
4.17.1, a memory corruption bug in JFS can be triggered by calling setxattr
twice with two different extended attribute names on the same file. This
vulnerability can be triggered by an unprivileged user with the ability to
create files and execute programs. A kmalloc call is incorrect, leading to
slab-out-of-bounds in jfs_xattr.
