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: net: usb: asix: hold PM usage ref to
avoid PM/MDIO + RTNL deadlock Prevent USB runtime PM (autosuspend) for AX88772* in bind. usbnet enables
runtime PM (autosuspend) by default, so disabling it via the usb_driver flag is ineffective. On AX88772B,
autosuspend shows no measurable power saving with current driver (no link partner, admin up/down). The
~0.453 W -> ~0.248 W drop on v6.1 comes from phylib powering the PHY off on admin-down, not from USB
autosuspend. The real hazard is that with runtime PM enabled, ndo_open() (under RTNL) may synchronously
trigger autoresume (usb_autopm_get_interface()) into asix_resume() while the USB PM lock is held. Resume
paths then invoke phylink/phylib and MDIO, which also expect RTNL, leading to possible deadlocks or PM
lock vs MDIO wake issues. To avoid this, keep the device runtime-PM active by taking a usage reference in
ax88772_bind() and dropping it in unbind(). A non-zero PM usage count blocks runtime suspend regardless of
userspace policy (.../power/control - pm_runtime_allow/forbid), making this approach robust against sysfs
overrides. Holding a runtime-PM usage ref does not affect system-wide suspend; system sleep/resume
callbacks continue to run as before. (CVE-2025-40120)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.104.3 or later.
