As a system runs and its memory becomes fragmented, allocating large,
physically contiguous regions of memory becomes increasingly difficult.
Much effort over the years has gone into avoiding the need to make such
allocations whenever possible, but there are times when they simply cannot
be avoided. The kernel's contiguous memory
allocator (CMA) subsystem attempts to make such allocations possible,
but it has never been a perfect solution. Suren Baghdasaryan is is trying
to improve that situation with the guaranteed
contiguous memory allocator patch set, which includes work from Minchan
Kim as well.

⚡ Empfohlene Sofortmaßnahmen
- 1. Perimeter-Inspektion: Relevante Portfreigaben und exponierte Endpunkte unverzüglich scannen.
- 2. Patch-Applikation: Hersteller-Hotfix einspielen oder betroffene Daemons in isolierte DMZ-Segmente überführen.
- 3. Telemetrie & EDR-Alerts: Prozessaufrufe und Child-Processes auf anomale Shell-Spawns überwachen.
