AI-suggested
A fix is available that involves canceling and draining the delayed work 'go_cfg_setup' at the start of hid_go_cfg_remove(), before acquiring the related mutex, to prevent use-after-free. Users should apply the updated Linux kernel versions that include this fix. No additional mitigation beyond applying the patch is indicated.
Description
A use-after-free vulnerability exists in the Linux kernel's hid-lenovo-go driver due to a delayed work item not being properly canceled during device removal. This can lead to a stale pointer dereference if the device is unbound shortly after probe, potentially causing kernel instability.
