Overview

CVE-2026-74374 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

md/raid1,raid10: fix error-path detection with md_cloned_bio()

Detect the error path using md_cloned_bio() instead of relying

on r1_bio in raid1 or r10_bio->read_slot in raid10, which may be

NULL or -1 after splitting and resubmitting a failed bio.

As a result, the error path may not be recognized and memory

allocations can incorrectly use GFP_NOIO instead of

(GFP_NOIO | __GFP_HIGH), which can lead to a deadlock under

memory pressure.

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.
