Vulnerability from fkie_nvd - Published: 2024-05-17 12:15 - Updated: 2025-09-26 17:05
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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.

Probablemente esto no sea un problema tan grande en sistemas donde la NVGPU es la \u00fanica GPU, pero en configuraciones de m\u00faltiples GPU conduce a una regresi\u00f3n en la que el m\u00f3dulo del kernel genera errores y provoca una congelaci\u00f3n de la representaci\u00f3n en todo el sistema. Esta confirmaci\u00f3n soluciona esa regresi\u00f3n moviendo los dos buffers necesarios para suspender y reanudar para que se desasignen durante la descarga del controlador en lugar de despu\u00e9s del inicio."
