CVE-2024-49982

8.8 · HIGH
Published Oct 21, 2024 linux CWE-416 EPSS 0.38% (31th pctl)

Overview

CVE-2024-49982 is a high-severity vulnerability affecting linux linux_kernel. It was published on October 21, 2024 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical Description

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

aoe: fix the potential use-after-free problem in more places

For fixing CVE-2023-6270, f98364e92662 ("aoe: fix the potential

use-after-free problem in aoecmd_cfg_pkts") makes tx() calling dev_put()

instead of doing in aoecmd_cfg_pkts(). It avoids that the tx() runs

into use-after-free.

Then Nicolai Stange found more places in aoe have potential use-after-free

problem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe()

and aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push

packet to tx queue. So they should also use dev_hold() to increase the

refcnt of skb->dev.

On the other hand, moving dev_put() to tx() causes that the refcnt of

skb->dev be reduced to a negative value, because corresponding

dev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(),

probe(), and aoecmd_cfg_rsp(). This patch fixed this issue.

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.
