Overview

CVE-2025-38607 is a high-severity vulnerability. It was published on August 19, 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: handle jset (if a & b ...) as a jump in CFG computation

BPF_JSET is a conditional jump and currently verifier.c:can_jump()

does not know about that. This can lead to incorrect live registers

and SCC computation.

E.g. in the following example:

1: r0 = 1;

2: r2 = 2;

3: if r1 & 0x7 goto +1;

4: exit;

5: r0 = r2;

6: exit;

W/o this fix insn_successors(3) will return only (4), a jump to (5)

would be missed and r2 won't be marked as alive at (3).

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-2025-38607?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2025-38607 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.
