Linux kernel AX88179_178A USB Ethernet driver out-of-bounds memory access

IdentifiersCVE-2022-2964CWE-119· Improper Restriction of Operations…

CVE-2022-2964 is a memory-safety vulnerability in the Linux kernel ASIX AX88179_178A USB 2.0/3.0 Gigabit Ethernet driver. Multiple out-of-bounds reads and potential out-of-bounds writes occur in the driver's ax88179_rx_fixup() receive-processing function. Insufficient bounds validation of device-controlled receive data can cause kernel memory disclosure or corruption.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An attacker able to trigger the vulnerable receive-processing path may disclose kernel memory through out-of-bounds reads or corrupt kernel memory through potential out-of-bounds writes. Consequences include system crash or denial of service and, depending on memory layout and attacker control, potential arbitrary code execution. The reported CVSS v3.1 vector is AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H.

Mitigation

If you can’t patch tonight, do this now.

No qualifying vendor mitigation is available. Where patching cannot occur immediately, reduce exposure by preventing untrusted users from attaching or controlling ASIX AX88179_178A-based USB Ethernet adapters and by restricting local access to affected systems.

Remediation

Patch, then assume compromise.

Install the Linux kernel update supplied by the operating-system vendor that incorporates the upstream fix for CVE-2022-2964. Fedora remediated the issue in stable kernel version 5.16.10. For affected Red Hat Enterprise Linux deployments, apply the applicable updated kernel, kernel-rt, or kpatch-patch errata for the installed product stream. Reboot after conventional kernel package installation; live-patch deployments should confirm that the updated live patch is loaded and active.
