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.

Added to KEV: 9 Apr 2025Federal remediation due: 30 Apr 2025

Description

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.

How Secuno handles this

Secuno correlates vulnerabilities like CVE-2024-53197 against the real software inventory on every managed device, as each hourly inventory arrives. Rather than a static severity, each match is scored in context: exploit availability, EPSS, the asset's exposure, and business criticality decide where it lands in the queue. Because it is on the CISA KEV list, a risk for it never ranks below high, and the update that fixes it moves to the Emergency patch lane. If an affected version is present anywhere across your portfolio, it surfaces automatically with a prioritised remediation path.
