CVE-2026-43072

A flaw was found in the drm/vc4 component of the Linux kernel. The platform_get_irq_byname() function, which returns an integer that can indicate an error, was not properly validated before being passed to devm_request_threaded_irq(). This oversight in error handling could potentially lead to system instability or resource exhaustion, resulting in a denial of service (DoS).
