CVE-2026-64553

Published Jul 27, 2026 EPSS 0.18% (7th pctl)

Overview

CVE-2026-64553 is a known-severity vulnerability. It was published on July 27, 2026.

Technical Description

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

net: psample: fix info leak in PSAMPLE_ATTR_DATA

psample open codes nla_put() presumably to avoid wiping

the data with 0s just to override it with packet data.

This open coding is missing clearing the pad, however,

each netlink attr is padded to 4B and data_len may

not be divisible by 4B.

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.
