CVE-2024-53197: 
Linux Kernel vulnerability analysis and mitigation

CVE-2024-53197 is a vulnerability discovered in the Linux kernel's ALSA USB audio driver affecting Extigy and Mbox devices. The vulnerability was disclosed on December 27, 2024, and involves potential out-of-bounds accesses that can occur when a malicious USB device provides an invalid bNumConfigurations value (NVD).

The vulnerability exists in the USB audio driver where a bogus device can provide a bNumConfigurations value that exceeds the initial value used in usbgetconfiguration for allocating dev->config. This can lead to out-of-bounds accesses later, particularly in usbdestroyconfiguration. The issue affects the kernel's handling of USB audio devices, specifically the Extigy and Mbox device configurations (Kernel Commit).

The vulnerability could allow an attacker with physical access to a system to potentially cause out-of-bounds memory accesses, which could lead to system crashes or potential privilege escalation. The issue specifically affects systems using USB audio devices, particularly Extigy and Mbox devices (Hacker News).

The vulnerability has been patched in the Linux kernel with a fix that validates the bNumConfigurations value before performing memory operations. Various Linux distributions have released updates incorporating this fix, including Ubuntu and Debian. Users are advised to update their systems to the latest kernel version that includes the patch (Debian Tracker).
