Technical description

In the Linux kernel, the following vulnerability has been resolved:

staging: gpib: fix unset padding field copy back to userspace

The introduction of a padding field in the gpib_board_info_ioctl is

showing up as initialized data on the stack frame being copyied back

to userspace in function board_info_ioctl. The simplest fix is to

initialize the entire struct to zero to ensure all unassigned padding

fields are zero'd before being copied back to userspace.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
