Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： ASoC: rockchip: rockchip_pdm: 在 set_fmt 中处理运行时电源管理（runtime PM）恢复失败的问题 rockchip_pdm_set_fmt() 函数在访问硬件寄存器之前会调用 pm_runtime_get_sync()，但其忽略了该函数的返回值。如果运行时恢复失败，函数将继续执行寄存器访问操作，而此时设备状态尚未确定（undefined）。 此修复将 pm_runtime_get_sync() 替换为 pm_runtime_resu

Vulnerability Title
ASoC: rockchip: rockchip_pdm: Handle runtime PM resume failures in set_fmt
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: rockchip: rockchip_pdm: Handle runtime PM resume failures in set_fmt
rockchip_pdm_set_fmt() calls pm_runtime_get_sync() before accessing
hardware registers, but ignores its return value.
If the runtime resume fails, the function continues to perform register
accesses while the device state is undefined.
Replace pm_runtime_get_sync() with pm_runtime_resume_and_get() and
return early on failure to avoid unpowered register accesses.
