  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ndrm/vc4: platform_get_irq_byname() returns an int\nplatform_get_irq_byname() will return a negative value if an error\nhappens, so it should be checked and not just passed directly into\ndevm_request_threaded_irq() hoping all will be ok.", "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)." ],
