Overview

CVE-2026-53092 is a high-severity vulnerability. It was published on June 24, 2026 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 linked reg delta tracking when src_reg == dst_reg

Consider the case of rX += rX where src_reg and dst_reg are pointers to

the same bpf_reg_state in adjust_reg_min_max_vals(). The latter first

modifies the dst_reg in-place, and later in the delta tracking, the

subsequent is_reg_const(src_reg)/reg_const_value(src_reg) reads the

post-{add,sub} value instead of the original source.

This is problematic since it sets an incorrect delta, which sync_linked_regs()

then propagates to linked registers, thus creating a verifier-vs-runtime

mismatch. Fix it by just skipping this corner case.

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.

How can CyberStrike help with CVE-2026-53092?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-53092 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
