Vulnerability in Linux kernel (CVE-2025-68287)
Summary
Vulnerability in Linux kernel (CVE-2025-68287). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: Fix race condition between concurrent dwc3_remove_requests() call paths
This patch addresses a race condition caused by unsynchronized
execution of multiple call paths invoking dwc3_remove_requests(),
leading to premature freeing of USB requests and subsequent crashes.
Three distinct execution paths interact with dwc3_remove_requests():
Path 1:
Triggered via dwc3_gadget_reset_interrupt() during USB reset
handling. The call stack includes:
dwc3_ep0_reset_state()dwc3_ep0_stall_and_restart()dwc3_ep0_out_start()dwc3_remove_requests()dwc3_gadget_del_and_unmap_request()
Path 2:
Also initiated from dwc3_gadget_reset_interrupt(), but through
dwc3_stop_active_transfers(). The call stack includes:
dwc3_stop_active_transfers()dwc3_remove_requests()dwc3_gadget_del_and_unmap_request()
Path 3:
Occurs independently during adb root execution, which triggers
USB function unbind and bind operations. The sequence includes:
gserial_disconnect()usb_ep_disable()dwc3_gadget_ep_disable()dwc3_remove_requests()with-ESHUTDOWNstatus
Path 3 operates asynchronously and lacks synchronization with Paths
1 and 2. When Path 3 completes, it disables endpoints and frees 'out'
requests. If Paths 1 or 2 are still processing these requests,
accessing freed memory leads to a crash due to use-after-free conditions.
To fix this added check for request completi…
