Linux Distros Unpatched Vulnerability : CVE-2026-68280

critical Nessus Plugin ID 334344

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - drm/bridge: cdns-dsi: Replace deprecated UNIVERSAL_DEV_PM_OPS() The deprecated UNIVERSAL_DEV_PM_OPS() macro uses the provided callbacks for both runtime PM and system sleep. This causes the DSI clocks to be disabled twice: once during runtime suspend and again during system suspend, resulting in a WARN message from the clock framework when attempting to disable already-disabled clocks. [ 84.384540] clk:231:5 already disabled [ 84.388314] WARNING: CPU: 2 PID: 531 at /drivers/clk/clk.c:1181 clk_core_disable+0xa4/0xac ...

Bridge and panel drivers should only deal with runtime PM, as the DRM framework manages system-wide power transitions through the bridge enable() and disable() hooks. (CVE-2026-68280)

Note that Nessus relies on the presence of the package as reported by the vendor.
