Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会开源的一个操作系统内核。 Linux kernel 5.1版本存在安全漏洞，该漏洞源于sound/soc/xilinx/xlnx_formatter_pcm.c中驱动数据在devm_request_irq之后才设置，中断处理程序通过dev_get_drvdata获取数据时可能将空指针传递给readl，导致崩溃。

Vulnerability Title
ASoC: xilinx: formatter_pcm: pass aud_drv_data to irq handlers
Source: CVE Program / CVE List V5
Vulnerability Description
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.
