  "details": "In the Linux kernel, the following vulnerability has been resolved:  auxdisplay: line-display: fix NULL dereference in linedisp_release  linedisp_release() currently retrieves the enclosing struct linedisp via to_linedisp(). That lookup depends on the attachment list, but the attachment may already have been removed before put_device() invokes the release callback. This can happen in linedisp_unregister(), and can also be reached from some linedisp_register() error paths.  In that case, to_linedisp() returns NULL and linedisp_release() dereferences it while freeing the display resources.  The struct device released here is the embedded linedisp-\u003edev used by linedisp_register(), so retrieve the enclosing object directly with container_of() instead.",
