CVE-2022-50236
In the Linux kernel, the following vulnerability has been resolved: iommu/mediatek: Fix crash on isr after kexec() If the system is rebooted via isr(), the IRQ handler might be triggered before the domain is initialized.
Does this matter?
Lower severity and a low EPSS score (0.15%). Track it; it rarely justifies an emergency change on its own.
