Kernel: X86_64_GENERIC (default), #0 build = the unpatched audit-source kernel.
Loaded kernel modules (kldstat):
Id Refs Address Size Name
1 5 0xffffffff80200000 1ad8538 kernel
2 1 0xffffffff81cd9000 7c288 ehci.ko
3 1 0xffffffff81d56000 8c778 xhci.ko
=> NO advansys, adwcam, amd, bt(buslogic), mpt, mfi, mpr, mps, isp, trm, sym,
sili, sbp, ahci-mpt-isp module loaded. The HBA drivers cited by
DF-2411/2415/2424/2428 are not present in the running kernel and there is
no matching PCI hardware to attach them to (see pciconf below).
camcontrol devlist (CAM-attached targets):
<QEMU QEMU DVD-ROM 2.5+> at scbus1 target 0 lun 0 (sg0,pass0,cd0)
=> The ONLY CAM peripheral is the QEMU DVD-ROM, reached via the PIIX3 IDE
controller (atapci0 / ata-cam), NOT a SCSI HBA. There is no SCSI HBA at
all, and no direct-access disk (da) or medium-changer (ch) target.
/dev SCSI peripheral nodes:
crw-r----- root operator /dev/cd0 (mode 0640 โ owner root, group operator)
crw------- root operator /dev/pass0 (mode 0600 โ root only)
crw------- root operator /dev/sg0 (mode 0600 โ root only)
crw------- root operator /dev/sga (mode 0600 โ root only)
crw------- root operator /dev/xpt0 (mode 0600 โ root only)
(no /dev/da*, no /dev/ch*)
pciconf -l (mass-storage / bridge devices):
isab1@pci0:0:1:0 class=0x060100 Intel 82371SB PIIX3 ISA bridge
atapci0@pci0:0:1:1 class=0x010180 Intel 82371AB PIIX3 IDE (WDMA2) <- the cd0 parent
virtio_pci1@pci0:0:4:0 class=0x010000 virtio block (the root disk, vtblk, NOT SCSI)
=> NO AdvanSys (0x10cd/0x1217 etc.), NO AMD 53c974 (0x1022/0x2020), NO BusLogic
(0x104b/*), NO LSI/Symbios/LSI53c895a, NO AHCI. The four HBA-driver
findings (advansys/adwcam/amd/bt) have no hardware to bind.
Unprivileged user (the PoC actor):
id maxx => uid=1001(maxx) gid=1001(maxx) groups=1001(maxx)
maxx is in NO privileged group (not wheel, not operator).
Unprivileged reachability probe:
$ su -m maxx -c "camcontrol devlist"
camcontrol: couldn't open /dev/xpt0: Permission denied
$ (as maxx) test -r/w on /dev/xpt0 /dev/sg0 /dev/cd0 /dev/pass0 => NO_ACCESS for all.
dmesg HBA scan (grep advansys|adw|amd|buslogic|bt|sili|trm|sym|mpt|isp|ahci|mfi|mpr|mps):
(no matches for any SCSI HBA driver โ only the ata-cam cd0 path)
