CVE-2026-53067

A flaw was found in the Linux kernel's PCI Peripheral Component Interconnect endpoint Message Signaled Interrupts MSI doorbell allocation. When MSI allocation fails, the system may attempt to free already freed memory, leading to a double-free vulnerability. This issue can result in memory...

CVE-2026-53051

A flaw was found in the Linux kernel. During a specific hardware reset sequence, the system attempts to access hardware registers before the PCI Express controller is fully powered on. This premature access can cause a Control Backbone CBB timeout, leading to system unresponsiveness. This issue c...
