In the Linux kernel, the following vulnerability has been resolved: scsi: mpt3sas: Fix possible resource leaks in mpt3sas_transport_port_add() In mpt3sas_transport_port_add(), if sas_rphy_add() returns error, sas_rphy_free() needs be called to free the resource allocated in sas_end_device_alloc(). Otherwise a kernel crash will happen: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000108 CPU: 45 PID: 37020 Comm: bash Kdump: loaded Tainted: G W 6.1.0-rc1+ #189 pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : device_del+0x54/0x3d0 lr : device_del+0x37c/0x3d0 Call trace: device_del+0x54/0x3d0 attribute_container_class_device_del+0x28/0x38 transport_remove_classdev+0x6c/0x80 attribute_container_device_trigger+0x108/0x110 transport_remove_device+0x28/0x38 sas_rphy_remove+0x50/0x78 [scsi_transport_sas] sas_port_delete+0x30/0x148 [scsi_transport_sas] do_sas_phy_delete+0x78/0x80 [scsi_transport_sas] device_for_each_child+0x68/0xb0 sas_remove_children+0x30/0x50 [scsi_transport_sas] sas_rphy_remove+0x38/0x78 [scsi_transport_sas] sas_port_delete+0x30/0x148 [scsi_transport_sas] do_sas_phy_delete+0x78/0x80 [scsi_transport_sas] device_for_each_child+0x68/0xb0 sas_remove_children+0x30/0x50 [scsi_transport_sas] sas_remove_host+0x20/0x38 [scsi_transport_sas] scsih_remove+0xd8/0x420 [mpt3sas] Because transport_add_device() is not called when sas_rphy_add() fails, the device is not added. When sas_rphy_remove() is subsequently called to remove the device in the remove() path, a NULL pointer dereference happens.
