CVE-2024-50234 (published 2024-11-09)
In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlegacy: Clear stale interrupts before resuming device

iwl4965 fails upon resume from hibernation on my laptop. The reason
seems to be a stale interrupt which isn't being cleared out before
interrupts are enabled. We end up with a race beween the resume
trying to bring things back up, and the restart work (queued form
the interrupt handler) trying to bring things down. Eventually
the whole thing blows up.

Fix the problem by clearing out any stale interrupts before
interrupts get enabled during resume.

Here's a debug log of the indicent:
