CVE-2026-23188

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

net: usb: r8152: fix resume reset deadlock

rtl8152 can trigger device reset during reset which

potentially can result in a deadlock:

**** DPM device timeout after 10 seconds; 15 seconds until panic ****

Call Trace:

The problem is that rtl8152 resume calls reset under

tp->control mutex while reset basically re-enters rtl8152

and attempts to acquire the same tp->control lock once

again.

Reset INACCESSIBLE device outside of tp->control mutex

scope to avoid recursive mutex_lock() deadlock.
