CVE-2024-27049 Information

Description

In the Linux kernel the following vulnerability has been resolved:

wifi: mt76: mt7925e: fix use-after-free in free_irq()

From commit a304e1b82808 ([PATCH] Debug shared irqs) there is a test to make sure the shared irq handler should be able to handle the unexpected event after deregistration. For this case let’s apply MT76_REMOVED flag to indicate the device was removed and do not run into the resource access anymore.
