CVE-2022-49118

5.5 · MEDIUM
Published Feb 26, 2025 linux EPSS 0.26% (18th pctl)

Overview

CVE-2022-49118 is a medium-severity vulnerability affecting linux linux_kernel. It was published on February 26, 2025 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:

scsi: hisi_sas: Free irq vectors in order for v3 HW

If the driver probe fails to request the channel IRQ or fatal IRQ, the

driver will free the IRQ vectors before freeing the IRQs in free_irq(),

and this will cause a kernel BUG like this:

------------[ cut here ]------------

kernel BUG at drivers/pci/msi.c:369!

Internal error: Oops - BUG: 0 [#1] PREEMPT SMP

Call trace:

free_msi_irqs+0x118/0x13c

pci_disable_msi+0xfc/0x120

pci_free_irq_vectors+0x24/0x3c

hisi_sas_v3_probe+0x360/0x9d0 [hisi_sas_v3_hw]

local_pci_probe+0x44/0xb0

kthread+0x180/0x190

ret_from_fork+0x10/0x20

---[ end trace b88990335b610c11 ]---

So we use devm_add_action() to control the order in which we free the

vectors.

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.
