# CVE-2026-53107

> 3.1 LOW

## Beschreibung

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

wifi: libertas: don't kill URBs in interrupt context

Serialization for the TX path was enforced by calling
usb_kill_urb()/usb_kill_anchored_urbs(), to prevent transmission before
a previous URB was completed. usb_tx_block() can be called from
interrupt context (e.g. in the HCD giveback path), so we can't always
use it to kill in-flight URBs.

Prevent sleeping during interrupt context by checking the tx_submitted
anchor for existing URBs. We now return -EBUSY, to indicate there's
a pending request.

## Patch verfügbar (OSV)

- Kernel ≥ 6.18.33
- Kernel ≥ 7.0.10
