Technical description

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

wifi: avoid kernel-infoleak from struct iw_point

struct iw_point has a 32bit hole on 64bit arches.

struct iw_point {

void __user *pointer; /* Pointer to the data (in user space) */

__u16 length; /* number of fields or size in bytes */

__u16 flags; /* Optional params */

};

Make sure to zero the structure to avoid disclosing 32bits of kernel data

to user space.

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.
