AI-suggested

A fix is available and has been applied in the Linux kernel. The remediation replaces the PM variant of write_cmd calls with their _nopm variants inside the suspend callback to avoid performing power management operations during suspend. Users should update to a Linux kernel version that includes the fix identified by the provided commit hashes.

Description

CVE-2026-23446 is a Linux kernel vulnerability in the net: usb: aqc111 driver where power management (PM) operations are improperly performed inside a suspend callback. This causes a deadlock by blocking a task holding the rtnl_lock, effectively locking up the networking stack. The issue arises because the suspend callback calls the PM variant of a write command, triggering a runtime resume that waits indefinitely. The fix replaces these calls with non-PM variants to prevent the deadlock.
