Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

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，以下漏洞已得到修复： i2c: viai2c-wmt：修复 wmt_i2c_probe() 中的时钟资源泄漏问题在 wmt_i2c_probe() 函数中，通过 of_clk_get() 获取 i2c->clk。如果后续任何操作失败，或者在模块卸载时，时钟的引用计数从未通过 clk_put() 进行递减，从而导致资源泄漏。现已改用 devm_clk_get()，以便时钟能够被自动管理并在适当时自动释放。

Vulnerability Title

i2c: viai2c-wmt: Fix clock leak in wmt_i2c_probe()

Source: CVE Program / CVE List V5

Vulnerability Description

In the Linux kernel, the following vulnerability has been resolved: i2c: viai2c-wmt: Fix clock leak in wmt_i2c_probe() In wmt_i2c_probe(), i2c->clk is acquired using of_clk_get(). If any subsequent operation fails or when the module is unloaded, the clock reference count is never decremented via clk_put(), leading to a resource leak. Switch to devm_clk_get() so that the clock is automatically managed and released.
