Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: media: venus: protect against spurious interrupts during probe Make sure the interrupt handler is initialized before the interrupt is registered. If the IRQ is registered before hfi_create(), it's possible that an interrupt fires before the handler setup is complete, leading to a NULL dereference. This error condition has been observed during system boot on Rb3Gen2.
