CVE-2024-53156

7.8 · HIGH
Published Dec 24, 2024 linux CWE-129 EPSS 0.24% (15th pctl)

Overview

CVE-2024-53156 is a high-severity vulnerability affecting linux linux_kernel. It was published on December 24, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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: ath9k: add range check for conn_rsp_epid in htc_connect_service()

I found the following bug in my fuzzer:

UBSAN: array-index-out-of-bounds in drivers/net/wireless/ath/ath9k/htc_hst.c:26:51

index 255 is out of range for type 'htc_endpoint [22]'

CPU: 0 UID: 0 PID: 8 Comm: kworker/0:0 Not tainted 6.11.0-rc6-dirty #14

Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014

Workqueue: events request_firmware_work_func

Call Trace:

<TASK>

dump_stack_lvl+0x180/0x1b0

__ubsan_handle_out_of_bounds+0xd4/0x130

htc_issue_send.constprop.0+0x20c/0x230

ath9k_wmi_cmd+0x41d/0x610

? mark_held_locks+0x9f/0xe0

...

Since this bug has been confirmed to be caused by insufficient verification

of conn_rsp_epid, I think it would be appropriate to add a range check for

conn_rsp_epid to htc_connect_service() to prevent the bug from occurrin

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.
