Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于drm/xe/ufence中预取ufence地址以捕获无效地址的问题，access_ok只检查地址溢出，因此也尝试读取地址以捕获从用户空间发送的无效地址。
