# CVE-2024-53197: Linux Kernel Out-of-Bounds Access Vulnerability

- Exploited (CISA KEV): yes, added 2025-04-09
- Published: 2024-12-27
- CVSS: 7.8 HIGH (v3.1)
- EPSS: 4.1% (91th percentile)
- CWE: CWE-787

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.
