CVE-2026-72273

Summary
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.
