Overview

CVE-2026-68295 is a high-severity vulnerability. It was published on August 10, 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:

LoongArch: BPF: Zero-extend signed ALU32 div/mod results

ALU32 operations write a 32-bit result and leave the upper 32 bits of

the BPF register zero. The LoongArch JIT sign-extends the result of

signed ALU32 BPF_DIV and BPF_MOD (off=1), so a negative 32-bit quotient

or remainder leaves bits 63:32 set in JITted code while the verifier

and interpreter model those bits as zero.

Keep sign-extension on the operands, which signed divide needs, and

zero-extend the ALU32 result after the divide or modulo instruction,

matching the unsigned ALU32 div/mod paths and every other ALU32

operation in this JIT.

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-2026-68295?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-68295 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.
