7.5 · HIGH
Published May 14, 2024 linux CWE-401 EPSS 0.77% (53th pctl)

Overview

CVE-2024-27393 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 14, 2024 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

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

xen-netfront: Add missing skb_mark_for_recycle

Notice that skb_mark_for_recycle() is introduced later than fixes tag in

commit 6a5bcd84e886 ("page_pool: Allow drivers to hint on SKB recycling").

It is believed that fixes tag were missing a call to page_pool_release_page()

between v5.9 to v5.14, after which is should have used skb_mark_for_recycle().

Since v6.6 the call page_pool_release_page() were removed (in

commit 535b9c61bdef ("net: page_pool: hide page_pool_release_page()")

and remaining callers converted (in commit 6bfef2ec0172 ("Merge branch

'net-page_pool-remove-page_pool_release_page'")).

This leak became visible in v6.8 via commit dba1b8a7ab68 ("mm/page_pool: catch

page_pool memory leaks").

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.
