What is CVE-2024-27411?

Official description
In the Linux kernel, the following vulnerability has been resolved:
drm/nouveau: keep DMA buffers required for suspend/resume
Nouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly. This is likely not as big an issue on systems where the NVGPU is the only GPU, but on multi-GPU set ups it leads to a regression where the kernel module errors and results in a system-wide rendering freeze.
This commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init.
Which versions are affected by CVE-2024-27411?
It affects 1 product.
Products include Linux kernel.
How do I fix CVE-2024-27411?
Apply the vendor's patch.
