Doc Text:
A vulnerability was found in the Linux kernel's S390 driver, where the path_event function can lead to a kernel panic if no driver is attached to a device or if the driver does not implement the function. This occurs when an FCES path-event is triggered without verifying the driver's availability first. The impact of this vulnerability can result in unexpected system crashes, affecting overall system stability.

Description OSIDB Bzimport 2024-07-16 12:27:43 UTC 
In the Linux kernel, the following vulnerability has been resolved:

s390/cio: verify the driver availability for path_event call

If no driver is attached to a device or the driver does not provide the
path_event function, an FCES path-event on this device could end up in a
kernel-panic. Verify the driver availability before the path_event
function call.
