Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: fbdev: efifb: fix memory leak in efifb_probe() Since commit 73ce73c30ba9 ("fbdev: Transfer video= option strings to caller; clarify ownership") the string returned from fb_get_options() is expected to be freed by the caller, but the string is not freed in efifb_probe(). Fix that by freeing the option string after setup.
