AnalysisCVE.org

In the Linux kernel, the following vulnerability has been resolved:

ALSA: usbusx2y: validate URB actual_length in interrupt callback

i_usx2y_in04_int() processes the interrupt URB data without checking urb->actual_length. A short transfer from a malfunctioning device would cause the handler to process uninitialized heap data from the kmalloc-allocated in04_buf, which is then copied to the mmap-accessible ctl_snapshot[] array.

Fix by using kzalloc() for in04_buf to zero-initialize the buffer, and adding an actual_length check to skip processing on short transfers while still resubmitting the URB.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
