一、漏洞信息
漏洞编号：CVE-2021-47037
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0
CVSS V2.0分值：
BaseScore：0.0 Low
Vector：CVSS：2.0/
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:ASoC: q6afe-clocks: fix reprobing of the driverQ6afe-clocks driver can get reprobed. For example if the APR servicesare restarted after the firmware crash. However currently Q6afe-clocksdriver will oops because hw.init will get cleared during first _probecall. Rewrite the driver to fill the clock data at runtime rather thanusing big static array of clocks.

Q6afe-clocks driver can get reprobed. For example if the APR services
are restarted after the firmware crash. However currently Q6afe-clocks
driver will oops because hw.init will get cleared during first _probe
call. Rewrite the driver to fill the clock data at runtime rather than
using big static array of clocks.
