CVE-2022-48805

7.8 · HIGH
Published Jul 16, 2024 linux CWE-125 EPSS 0.32% (24th pctl)

Overview

CVE-2022-48805 is a high-severity vulnerability affecting linux linux_kernel. It was published on July 16, 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:

net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup

ax88179_rx_fixup() contains several out-of-bounds accesses that can be

triggered by a malicious (or defective) USB device, in particular:

- The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds,

causing OOB reads and (on big-endian systems) OOB endianness flips.

- A packet can overlap the metadata array, causing a later OOB

endianness flip to corrupt data used by a cloned SKB that has already

been handed off into the network stack.

- A packet SKB can be constructed whose tail is far beyond its end,

causing out-of-bounds heap data to be considered part of the SKB's

data.

I have tested that this can be used by a malicious USB device to send a

bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response

that contains random kernel heap data.

It's probably also possible to get OOB writes from this on a

little-endia

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.
