Technical description

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

md/raid1,raid10: don't ignore IO flags

If blk-wbt is enabled by default, it's found that raid write performance

is quite bad because all IO are throttled by wbt of underlying disks,

due to flag REQ_IDLE is ignored. And turns out this behaviour exist since

blk-wbt is introduced.

Other than REQ_IDLE, other flags should not be ignored as well, for

example REQ_META can be set for filesystems, clearing it can cause priority

reverse problems; And REQ_NOWAIT should not be cleared as well, because

io will wait instead of failing directly in underlying disks.

Fix those problems by keep IO flags from master bio.

Fises: f51d46d0e7cb ("md: add support for REQ_NOWAIT")

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-2025-22125?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2025-22125 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.
