# CVE-2026-74642

> 3.1 LOW

## Beschreibung

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

ALSA: usb: Fix UAF at delayed release of MIDI2 EPs

The recent fix for UAF in ump_to_endpoint() caused another UAF because
it tries to dereference the UMP endpoint object, but this might be
executed at a delayed context where the endpoint has been already
released.

Add private_free to clear the associated data for avoiding the further
dereference for delayed releases.

## Patch verfügbar (OSV)

- Kernel ≥ 6.6.152
- Kernel ≥ 6.12.104
- Kernel ≥ 6.18.45
- Kernel ≥ 7.1.9
