Vulnerability Title
ASoC: codecs: simple-mux: Fix enum control bounds check
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: simple-mux: Fix enum control bounds check simple_mux_control_put() rejects values greater than e->items, but enum control values are zero based. For the two-entry mux used by this driver, valid values are 0 and 1, so value 2 must be rejected as well. Accepting e->items can store an invalid mux state, pass it to the GPIO setter, and pass it on to the DAPM mux update path where it is used as an index into the enum text array. Use the same >= e->items check used by the ASoC enum helpers.

Linux kernel 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Linux kernel是美国Linux基金会开源的一款操作系统内核。 Linux kernel 5.11版本存在安全漏洞，该漏洞源于simple_mux_control_put函数对枚举控件边界检查不当，可接受无效的MUX状态，将其传递给GPIO设置器和DAPM MUX更新路径，并作为索引使用，可能导致系统异常。
