CVE-2024-53150: ALSA: usb-audio: Fix out of bounds reads when finding clock sources

HighCVSS 7.1 · v3.1KEVWeaponized Fix available

Noroxi assessment

Priority: Plan (action score 58/100)

  • 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: 1.3% (FIRST EPSS); higher than 71.9% 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 096bb5b43edf755bc4477e64004fa3a20539ec2f, 4.20, 45a92cbc88e4013bfed7fd2ccab3ade45f8e896b; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1.

Add it to your regular patch cycle. Upgrade to Linux Linux 096bb5b43edf755bc4477e64004fa3a20539ec2f, 4.20, 45a92cbc88e4013bfed7fd2ccab3ade45f8e896b; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1 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 out of bounds reads when finding clock sources The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check.

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.
