Overview

CVE-2024-45023 is a high-severity vulnerability. It was published on September 11, 2024 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:

md/raid1: Fix data corruption for degraded array with slow disk

read_balance() will avoid reading from slow disks as much as possible,

however, if valid data only lands in slow disks, and a new normal disk

is still in recovery, unrecovered data can be read:

raid1_read_request

read_balance

raid1_should_read_first

-> return false

choose_best_rdev

-> normal disk is not recovered, return -1

choose_bb_rdev

-> missing the checking of recovery, return the normal disk

-> read unrecovered data

Root cause is that the checking of recovery is missing in

choose_bb_rdev(). Hence add such checking to fix the problem.

Also fix similar problem in choose_slow_rdev().

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.
