Impact
The issue appears in the Qualcomm display clock controller (dispcc-eliza) driver of the Linux kernel. When the ELIZA board’s device tree enables the display clock controller, but no display hardware is present, the root clock generator (RCG) fails to update its configuration during probe, emitting a warning and potentially stalling the initialization of the clock tree. The resulting mis‑configuration can prevent the display subsystem and any dependent services from starting, effectively denying service on the host. The weakness is an improper initialization of the clock hardware, which can be classified as CWE-703.
Affected Systems
This vulnerability affects Linux kernel builds that include the Eliza EVK board description (eliza-cqs-evk.dts). The flaw resides in drivers/clk/qcom/clk-rcg2.c and dispcc-eliza.c. No specific kernel release is listed; any kernel that contains this code path and supports the Eliza device tree is potentially impacted, except for builds patched with the commit referenced in the description.
Risk and Exploitability
The fault is triggered during normal boot by the presence of an enabled clock controller node in the device tree. Based on the description, it is inferred that an attacker would need local system access or the ability to modify the kernel or device tree to exploit it, which typically requires root privileges. No CVSS or EPSS scores are provided, and the vulnerability is not listed in the CISA KEV catalog, indicating a modest risk that primarily affects device reliability and stability rather than confidentiality or integrity.
