Linux Kernel Zorro7xx Resource Leak Vulnerability

A resource leak vulnerability has been identified in the Linux kernel's SCSI Zorro7xx driver. The issue arises in the 'zorro7xx_remove_one()' function, where an error handling path releases a resource that is not properly freed in the removal process. This oversight can lead to a resource leak, as certain memory mappings created by 'ioremap()' are not being undone. The vulnerability has been addressed by adding the missing 'iounmap()' call in the removal function.

Impact

Exploitation of this vulnerability could lead to a resource leak, causing memory to be improperly managed and potentially leading to degraded system performance or stability.
