CVE-2024-35938

5.5 · MEDIUM
Published May 19, 2024 linux EPSS 0.21% (11th pctl)

Overview

CVE-2024-35938 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 19, 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:

wifi: ath11k: decrease MHI channel buffer length to 8KB

Currently buf_len field of ath11k_mhi_config_qca6390 is assigned

with 0, making MHI use a default size, 64KB, to allocate channel

buffers. This is likely to fail in some scenarios where system

memory is highly fragmented and memory compaction or reclaim is

not allowed.

There is a fail report which is caused by it:

kworker/u32:45: page allocation failure: order:4, mode:0x40c00(GFP_NOIO|__GFP_COMP), nodemask=(null),cpuset=/,mems_allowed=0

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.
