CVE-2026-64342 Details
Description
In the Linux kernel, the following vulnerability has been resolved: USB: iowarrior: fix use-after-free on disconnect Submitted write URBs are not stopped on close() and therefore need to be stopped unconditionally on disconnect() to avoid use-after-free in the completion handler.
A use-after-free vulnerability has been identified in the Linux kernel's USB Iowarrior driver. This issue arises because submitted write URBs are not halted when the device is closed, leading to a potential use-after-free scenario in the completion handler. The vulnerability is present in the stable versions of the Linux kernel.
Users can upgrade to the latest stable version of the Linux kernel, where this vulnerability has been addressed.
