Descriptions

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

fbdev: imsttfb: fix a resource leak in probe

I've re-written the error handling but the bug is that if init_imstt()
fails we need to call iounmap(par->cmap_regs).

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: fbdev: imsttfb: corrige una fuga de recursos en la sonda. He reescrito el manejo de errores, pero el error es que si init_imstt() falla, debemos llamar a iounmap(par-> cmap_regs).
