CVE-2024-27032

6.3 · MEDIUM
Published May 1, 2024 linux CWE-835 EPSS 0.29% (21th pctl)

Overview

CVE-2024-27032 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 1, 2024 and has a CVSS 3.1 base score of 6.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.3, 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:

f2fs: fix to avoid potential panic during recovery

During recovery, if FAULT_BLOCK is on, it is possible that

f2fs_reserve_new_block() will return -ENOSPC during recovery,

then it may trigger panic.

Also, if fault injection rate is 1 and only FAULT_BLOCK fault

type is on, it may encounter deadloop in loop of block reservation.

Let's change as below to fix these issues:

- remove bug_on() to avoid panic.

- limit the loop count of block reservation to avoid potential

deadloop.

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.
