Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: xilinx: formatter_pcm: pass aud_drv_data to irq handlers

The irq handlers take a struct device pointer and call dev_get_drvdata() to obtain the driver data. However, the driver data is only set at the end of probe, after devm_request_irq(), so an interrupt taken in between causes the handlers to pass a NULL pointer to readl() and crash.

Pass the private data directly as the devm_request_irq() argument instead of the device pointer, matching what the handlers expect.
