Overview

CVE-2022-50167 is a high-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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: fix potential 32-bit overflow when accessing ARRAY map element

If BPF array map is bigger than 4GB, element pointer calculation can

overflow because both index and elem_size are u32. Fix this everywhere

by forcing 64-bit multiplication. Extract this formula into separate

small helper and use it consistently in various places.

Speculative-preventing formula utilizing index_mask trick is left as is,

but explicit u64 casts are added in both places.

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.
