Overview

AI description

Automated description summarized from trusted sources.

CVE-2024-53197 is a privilege escalation vulnerability found in the USB sub-component of the Linux kernel. It stems from improper handling of the `bNumConfigurations` value in the ALSA USB audio subsystem, which can lead to out-of-bounds memory accesses. This vulnerability could allow an attacker with physical access to the system, through a malicious USB device, to manipulate system memory, potentially escalating privileges or executing arbitrary code. It has been identified as being exploited in targeted attacks, including being part of an exploit chain used to compromise an Android phone in December 2024.

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.
