CVE-2025-21923

HIGH

Linux Kernel 6.6.79-6.6.82, 6.12.16-6.12.18, 6.13.4-6.13.6 - Use-After-Free in HID Steam Device Detachment

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: HID: hid-steam: Fix use-after-free when detaching device When a hid-steam device is removed it must clean up the client_hdev used for intercepting hidraw access. This can lead to scheduling deferred work to reattach the input device. Though the cleanup cancels the deferred work, this was done before the client_hdev itself is cleaned up, so it gets rescheduled. This patch fixes the ordering to make sure the deferred work is properly canceled.
