{"id":"DEBIAN-CVE-2024-26892","details":"In the Linux kernel, the following vulnerability has been resolved:  wifi: mt76: mt7921e: 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.
