Descriptions
In the Linux kernel, the following vulnerability has been resolved:
ipack: ipoctal: fix module reference leak
A reference to the carrier module was taken on every open but was only
released once when the final reference to the tty struct was dropped.
Fix this by taking the module reference and initialising the tty driver
data when installing the tty.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ipack: ipoctal: reparar fuga de referencia del módulo. Se tomó una referencia al módulo portador en cada apertura, pero solo se publicó una vez cuando se eliminó la referencia final a la estructura tty. Solucione este problema tomando la referencia del módulo e inicializando los datos del controlador tty al instalar el tty.
