CVE-2026-23188

Estado: AnalizadaMedia (5.5)—

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:

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.
