CVE-2026-64461

In the Linux kernel, the following vulnerability has been resolved: PCI: mediatek: Fix IRQ domain leak when port fails to enable When mtkpcieenableport fails, mtkpcieportfree removes the port from pcie-ports and frees the port structure. However, the IRQ domains set up earlier by...

CVE-2026-64461

The CVE-2026-64461 entry concerns a Linux kernel PCIe Mediatek issue where IRQ domains are leaked when a port fails to enable. The fix refactors IRQ teardown into a per-port helper (mtk_pcie_irq_teardown_port()) and invokes it from the setup path when mtk_pcie_enable_port() fails. This ensures IR...
