Overview

CVE-2026-45967 is a medium-severity vulnerability. It was published on May 27, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

bpf: Return proper address for non-zero offsets in insn array

The map_direct_value_addr() function of the instruction

array map incorrectly adds offset to the resulting address.

This is a bug, because later the resolve_pseudo_ldimm64()

function adds the offset. Fix it. Corresponding selftests

are added in a consequent commit.

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.
