Published Dec 27, 2024 linux CWE-476 EPSS 0.22% (13th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-53233 is a medium-severity vulnerability affecting linux linux_kernel. It was published on December 27, 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:

unicode: Fix utf8_load() error path

utf8_load() requests the symbol "utf8_data_table" and then checks if the

requested UTF-8 version is supported. If it's unsupported, it tries to

put the data table using symbol_put(). If an unsupported version is

requested, symbol_put() fails like this:

kernel BUG at kernel/module/main.c:786!

RIP: 0010:__symbol_put+0x93/0xb0

Call Trace:

<TASK>

? __die_body.cold+0x19/0x27

? die+0x2e/0x50

? do_trap+0xca/0x110

? do_error_trap+0x65/0x80

? __symbol_put+0x93/0xb0

? exc_invalid_op+0x51/0x70

? __symbol_put+0x93/0xb0

? asm_exc_invalid_op+0x1a/0x20

? __pfx_cmp_name+0x10/0x10

? __symbol_put+0x93/0xb0

? __symbol_put+0x62/0xb0

utf8_load+0xf8/0x150

That happens because symbol_put() expects the unique string that

identify the symbol, instead of a pointer to the loaded symbol. Fix that

by using such string.

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.
