kernel: Kernel: Denial of Service in pci_endpoint_test due to zero-length DMA mapping

A flaw was found in the Linux kernel's pciendpointtest module. A local attacker with low privileges could exploit this vulnerability by providing a zero-length Direct Memory Access DMA mapping to the dmamapsingle function. This improper input validation can lead to a kernel panic, resulting in a...

CVE-2025-23140

CVE-2025-23140 affects the Linux kernel PCI Endpoint Test driver. The issue arose when devm_request_irq() failed in pci_endpoint_test_request_irq(): some IRQs were not released, leaving /proc/irq entries and triggering a WARN in fs/proc/generic.c (remove_proc_entry). The root cause is that pci_en...
