CVE-2025-40115

In CVE-2025-40115, the Linux kernel scsi/mpt3sas driver fixes a crash during transport_port_remove() when logging messages with dev_printk() to a SAS port that may already be partially unregistered or freed. The fix switches logging to ioc_info() (PCI device) which remains valid until driver remo...

CVE-2025-40117

CVE-2025-40117 affects the Linux kernel’s PCI Endpoint Test driver. The root cause is an array underflow in pci_endpoint_test_bar() when a negative value is passed to pci_endpoint_test_ioctl(). This followed the addition of NO_BAR (-1) to the pci_barno enum, effectively turning the enum from unsi...

CVE-2025-40145: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: PCI/pwrctrl: Fix double cleanup on devmaddactionorreset failure When devmaddactionorreset fails, it calls the passed cleanup function. Hence the caller must not repeat that cleanup. Replace the "goto errregulatorfree" by the actu...
