CVE-2026-89553

Описание

In the Linux kernel, the following vulnerability has been resolved: nouveau/gem: reserve the bo in the info ioctl around the vma lookup In the non-uvmm path, there could be a race between the info lookup finding the vma, and the gem close path closing the vma leading to a use-after-free. Spotted with the help of Opus 4.6.

A flaw was found in the Linux kernel's nouveau/gem component. A race condition exists where the graphics execution manager (GEM) close path can close a virtual memory area (VMA) while an information lookup is still trying to access it. This timing issue leads to a use-after-free vulnerability, which could allow a local attacker to potentially achieve arbitrary code execution or cause a denial of service.
