Overview

CVE-2025-71270 is a medium-severity vulnerability. It was published on March 18, 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:

LoongArch: Enable exception fixup for specific ADE subcode

This patch allows the LoongArch BPF JIT to handle recoverable memory

access errors generated by BPF_PROBE_MEM* instructions.

When a BPF program performs memory access operations, the instructions

it executes may trigger ADEM exceptions. The kernel’s built-in BPF

exception table mechanism (EX_TYPE_BPF) will generate corresponding

exception fixup entries in the JIT compilation phase; however, the

architecture-specific trap handling function needs to proactively call

the common fixup routine to achieve exception recovery.

do_ade(): fix EX_TYPE_BPF memory access exceptions for BPF programs,

ensure safe execution.

Relevant test cases: illegal address access tests in module_attach and

subprogs_extable of selftests/bpf.

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.
