ALSA: usb-audio: Fix potential memory leaks
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
- 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 0604e5e5537af099ea2f6dfd892afe5c92db8a80, 0672215994e2347a9b4f145e2bc1709b1e01cee3, 28d8d267af5d73f91d7640cbdb4024703256e36c.
Low priority for now. Upgrade to Linux Linux 0604e5e5537af099ea2f6dfd892afe5c92db8a80, 0672215994e2347a9b4f145e2bc1709b1e01cee3, 28d8d267af5d73f91d7640cbdb4024703256e36c or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential memory leaks When the driver hits -ENOMEM at allocating a URB or a buffer, it aborts and goes to the error path that releases the all previously allocated resources. However, when -ENOMEM hits at the middle of the sync EP URB allocation loop, the partially allocated URBs might be left without released, because ep->nurbs is still zero at that point. Fix it by setting ep->nurbs at first, so that the error handler loops over the full URB list.
