AI-suggested
A fix is available and has been applied in Linux kernel versions after 5.13. Users should update to a fixed kernel version that includes the patch moving vbus draw to a workqueue context to prevent kernel panics related to this issue.
Description
A vulnerability in the Linux kernel's USB DWC3 gadget driver was fixed by moving the vbus draw operation to a workqueue context. Previously, the function dwc3_gadget_vbus_draw() could be called from an atomic context but invoked power-supply-core APIs that may sleep, potentially causing a kernel panic. The fix involves deferring this operation to a workqueue to avoid sleeping in atomic context.
