Unsanitized input (rootname) can overflow a buffer, leading potentially to arbitrary code execution or possibly unspecified other impact.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
