CVE-2026-53051

The CVE-2026-53051 issue is a Linux kernel PCIe race in the NVIDIA Tegra194 CBB path. When PERST# toggles (assert → deassert → assert → deassert), the code sequence calls pci_epc_deinit_notify() and dw_pcie_ep_cleanup() before the controller core is powered on, causing a CBB timeout at DBI regist...
