Overview

CVE-2024-41082 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 29, 2024 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:

nvme-fabrics: use reserved tag for reg read/write command

In some scenarios, if too many commands are issued by nvme command in

the same time by user tasks, this may exhaust all tags of admin_q. If

a reset (nvme reset or IO timeout) occurs before these commands finish,

reconnect routine may fail to update nvme regs due to insufficient tags,

which will cause kernel hang forever. In order to workaround this issue,

maybe we can let reg_read32()/reg_read64()/reg_write32() use reserved

tags. This maybe safe for nvmf:

1. For the disable ctrl path, we will not issue connect command

2. For the enable ctrl / fw activate path, since connect and reg_xx()

are called serially.

So the reserved tags may still be enough while reg_xx() use reserved tags.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
