CVE-2022-49095 Details
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: zorro7xx: Fix a resource leak in zorro7xx_remove_one() The error handling path of the probe releases a resource that is not freed in the remove function. In some cases, a ioremap() must be undone. Add the missing iounmap() call in the remove function.
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.
