"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nata: libata-transport: fix error handling in ata_tdev_add()\n\nIn ata_tdev_add(), the return value of transport_add_device() is\nnot checked. As a result, it causes null-ptr-deref while removing\nthe module, because transport_remove_device() is called to remove\nthe device that was not added.\n\nUnable to handle kernel NULL pointer dereference at virtual address 00000000000000d0\nCPU: 13 PID: 13603 Comm: rmmod Kdump: loaded Tainted: G W 6.1.0-rc3+ #36\npstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--)\npc : device_del+0x48/0x3a0\nlr : device_del+0x44/0x3a0\nCall trace:\n device_del+0x48/0x3a0\n attribute_container_class_device_del+0x28/0x40\n transport_remove_classdev+0x60/0x7c\n attribute_container_device_trigger+0x118/0x120\n transport_remove_device+0x20/0x30\n ata_tdev_delete+0x24/0x50 [libata]\n ata_tlink_delete+0x40/0xa0 [libata]\n ata_tport_delete+0x2c/0x60 [libata]\n ata_port_detach+0x148/0x1b0 [libata]\n ata_pci_remove_one+0x50/0x80 [libata]\n ahci_remove_one+0x4c/0x8c [ahci]\n\nFix this by checking and handling return value of transport_add_device()\nin ata_tdev_add().
