Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> exfat: fix refcount leak in exfat_find<br /> <br /> Fix refcount leaks in `exfat_find` related to `exfat_get_dentry_set`.<br /> <br /> Function `exfat_get_dentry_set` would increase the reference counter of<br /> `es-&gt;bh` on success.
