In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fix nvkm_device leak on aperture removal failure When aperture_remove_conflicting_pci_devices() fails during probe, the error path returns directly without unwinding the nvkm_device that was just allocated by nvkm_device_pci_new(). This leaks both the device wrapper and the pci_enable_device() reference taken inside it. Jump to the existing fail_nvkm label so nvkm_device_del() runs and balances both. The leak was introduced when the intermediate nvkm_device_del() between detection and aperture removal was dropped in favor of creating the pci device once.
AI Analysis
Technical Summary
The Linux kernel nouveau DRM driver contains a resource leak vulnerability (CVE-2026-52904) caused by improper error handling during PCI device probing. Specifically, when aperture_remove_conflicting_pci_devices() fails, the error path returns without calling nvkm_device_del(), which would free the allocated nvkm_device and release the pci_enable_device() reference. This leak was introduced after a code change that removed an intermediate nvkm_device_del() call. The vulnerability leads to memory and device reference leaks, potentially impacting system stability.
Potential Impact
The vulnerability results in a resource leak (memory and PCI device references) in the Linux kernel nouveau DRM driver. This can degrade system availability by exhausting resources over time. There is no impact on confidentiality or integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, monitoring system resource usage related to nouveau devices may help detect issues. No official fix or patch links are currently provided.
