CVE-2024-53197: ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices

Noroxi assessment

Priority: This week (action score 62/100)

  • CISA has confirmed exploitation in the wild (Apr 9, 2025). Remediation deadline for US federal agencies: Apr 30, 2025.
  • Probability of exploitation in the next 30 days: 4.1% (FIRST EPSS); higher than 90.8% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0b4ea4bfe16566b84645ded1403756a2dc4e0f19, 379d3b9799d9da953391e973b934764f01e03960, 62dc01c83fa71e10446ee4c31e0e3d5d1291e865.

Don’t wait for the next maintenance window. Upgrade to Linux Linux 0b4ea4bfe16566b84645ded1403756a2dc4e0f19, 379d3b9799d9da953391e973b934764f01e03960, 62dc01c83fa71e10446ee4c31e0e3d5d1291e865 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

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.

Vulnrichment: CISA's decision-tree inputs.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Apr 9, 2025. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Apr 30, 2025.
