Echo: linux: security update to 6.1.170-1

medium Tenable Cloud Security Plugin ID 458658

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: usb: dwc2: gadget: Fix
spin_lock/unlock mismatch in dwc2_hsotg_udc_stop() dwc2_gadget_exit_clock_gating() internally calls
call_gadget() macro, which expects hsotg->lock to be held since it does spin_unlock/spin_lock around the
gadget driver callback invocation. However, dwc2_hsotg_udc_stop() calls dwc2_gadget_exit_clock_gating()
without holding the lock. This leads to: - spin_unlock on a lock that is not held (undefined behavior) -
The lock remaining held after dwc2_gadget_exit_clock_gating() returns, causing a deadlock when
spin_lock_irqsave() is called later in the same function. Fix this by acquiring hsotg->lock before calling
dwc2_gadget_exit_clock_gating() and releasing it afterwards, which satisfies the locking requirement of
the call_gadget() macro. (CVE-2026-31756)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
