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，已修复以下漏洞： drm/xe/i2c：在解绑（unbind）时禁用中断（IRQ） 目前，在解绑路径中， 结构体在 SGUnit 中断被禁用之前就被释放，若在此短暂时间窗口内发生 I2C 中断，则可能导致 Use-After-Free（UAF，即释放后使用）漏洞。通过在 函数中显式禁用 I2C 中断，修复了此问题。 （该补丁源自提交 8ba5c8b8ab3fd362267c11df2cd5a90ee46f6e24 的 cherry-pick）

Vulnerability Title
drm/xe/i2c: Disable IRQ on unbind
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: drm/xe/i2c: Disable IRQ on unbind Currently, struct xe_i2c is freed before SGUnit IRQ is disabled in unbind path, leaving a potential UAF in case I2C IRQ is hit during this small window. Explicitly disable I2C IRQ in xe_i2c_remove() and fix this. (cherry picked from commit 8ba5c8b8ab3fd362267c11df2cd5a90ee46f6e24)
