In the Linux kernel, the following vulnerability has been resolved: ceph: fix a buffer leak in __ceph_setxattr() The old_blob in __ceph_setxattr() can store ci->i_xattrs.prealloc_blob value during the retry. However, it is never called the ceph_buffer_put() for the old_blob object. This patch fixes the issue of the buffer leak.
