CVE-2026-46074

Опубликовано: 27 мая 2026
Источник: redhat

Описание

In the Linux kernel, the following vulnerability has been resolved: spi: ch341: fix memory leaks on probe failures Make sure to deregister the controller, disable pins, and kill and free the RX URB on probe failures to mirror disconnect and avoid memory leaks and use-after-free. Also add an explicit URB kill on disconnect for symmetry (even if that is not strictly required as USB core would have stopped it in the current setup).

A flaw was found in the Linux kernel, specifically within the spi: ch341 driver. This vulnerability occurs during probe failures, leading to memory leaks and use-after-free conditions. These issues can result in system instability or a denial of service, potentially allowing an attacker to impact system availability.
