How to fix?

Upgrade SLES:15.4 kernel-default to version 5.14.21-150400.24.133.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default package and not the kernel-default package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

regulator: da9211: Use irq handler when ready

If the system does not come from reset (like when it is kexec()), the regulator might have an IRQ waiting for us.

If we enable the IRQ handler before its structures are ready, we crash.

This patch fixes:
