CVE-2023-53446

CVE-2023-53446 is a Linux kernel issue affecting PCI/ASPM handling for multi-function devices (MFD). The root cause is a use-after-free: pcie_link_state->downstream pointed to the function’s pci_dev and was not cleared when function 0 was removed, leading to dereference during ASPM policy chan...
