Linux Kernel ALSA usb-audio OOB via bNumConfigurations
CVE-2024-53197 Published on December 27, 2024
ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices
A bogus device can provide a bNumConfigurations value that exceeds the
initial value used in usb_get_configuration for allocating dev->config.
This can lead to out-of-bounds accesses later, e.g. in
usb_destroy_configuration.
Known Exploited Vulnerability
This Linux Kernel Out-of-Bounds Access Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. Linux Kernel contains an out-of-bounds access vulnerability in the USB-audio driver that allows an attacker with physical access to the system to use a malicious USB device to potentially manipulate system memory, escalate privileges, or execute arbitrary code.
The following remediation steps are recommended / required by April 30, 2025: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Vulnerability Analysis
CVE-2024-53197 can be exploited with local system access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. This vulnerability is known to be actively exploited by threat actors. The potential impact of an exploit of this vulnerability is considered to be very high.
Weakness Type
What is a Memory Corruption Vulnerability?
The software writes data past the end, or before the beginning, of the intended buffer. Typically, this can result in corruption of data, a crash, or code execution. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent write operation then produces undefined or unexpected results.
CVE-2024-53197 has been classified to as a Memory Corruption vulnerability or weakness.
