CVE-2026-53324

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: mana: Use pci_name() for debugfs directory naming<br /> <br /> Use pci_name(pdev) for the per-device debugfs directory instead of<br /> hardcoded "0" for PFs and pci_slot_name(pdev-&gt;slot) for VFs. The<br /> previous approach had two issues:<br /> <br /> 1. pci_slot_name() dereferences pdev-&gt;slot, which can be NULL for VFs<br /> in environments like generic VFIO passthrough or nested KVM,<br /> causing a NULL pointer dereference.<br /> <br /> 2. Multiple PFs would all use "0", and VFs across different PCI<br /> domains or buses could share the same slot name, leading to<br /> -EEXIST errors from debugfs_create_dir().<br /> <br /> pci_name(pdev) returns the unique BDF address, is always valid, and is<br /> unique across the system.
