In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau: Fix bridge reference leak in nv1a_ram_new()

pci_get_domain_bus_and_slot() takes a reference to the PCI device, which is never released once the memory size has been read from its config space. Drop the reference before returning.

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.21 %
Percentile among all scored CVEs: 11
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
