In the Linux kernel, the following vulnerability has been resolved:

ecryptfs: release message context on send failure

ecryptfs_send_message_locked() moves a message context from the free
list to the allocated list before sending the request to the userspace
daemon.

If ecryptfs_send_miscdev() fails, the context is left on the
allocated list and cannot be reused. Move it back to the free list on
failure and clear the caller's pointer.
