Quick assessment

Affected
Linux Linux
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.

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s390/cio模块中发现驱动可用性验证问题。在调用path_event之前，如果没有驱动程序附加到设备或驱动程序不提供path_event，则可能会导致内核崩溃。
