CVE-2024-45012: nouveau/firmware: use dma non-coherent allocator

Noroxi assessment

Priority: Monitor (action score 22/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Linux Linux 57ca481fca97ca4553e8c85d6a94baf4cb40c40e, 9b340aeb26d50e9a9ec99599e2a39b035fac978e, cc29c5546c6a373648363ac49781f1d74b530707.

Low priority for now. Upgrade to Linux Linux 57ca481fca97ca4553e8c85d6a94baf4cb40c40e, 9b340aeb26d50e9a9ec99599e2a39b035fac978e, cc29c5546c6a373648363ac49781f1d74b530707 or later.
