UBUNTU-CVE-2025-68327: Low severity ubuntu/linux vulnerability

Q: Which systems are realistically exposed to this issue?

The reported failure occurs on the Renesas RZ/G3S SoC using the renesas_usbhs driver. It requires a USB ECM gadget to be configured through configfs and bound to the 11e20000.usb UDC.

Q: What action triggers the failure?

The synchronous external abort is triggered when the renesas_usbhs driver is unbound after completing the described USB gadget configuration sequence. The provided reproduction performs the unbind by writing 11e20000.usb to /sys/bus/platform/drivers/renesas_usbhs/unbind.

Q: Does this affect a default Ubuntu installation?

The provided information only demonstrates the issue after manually loading USB gadget modules, creating a configfs gadget, configuring an ECM function, binding it to the UDC, and then unbinding the driver. It does not state that this configuration is enabled by default.

In the Linux kernel, the following vulnerability has been resolved: usb: renesasusbhs: Fix synchronous external abort on unbind A synchronous external abort occurs on the Renesas RZ/G3S SoC if unbind is executed after the configuration sequence described above: modprobe usbfecm modprobe libcomposite modprobe configfs cd /sys/kernel/config/usbgadget mkdir -p g1 cd g1 echo "0x1d6b" > idVendor echo "0x0104" > idProduct mkdir -p strings/0x409 echo "0123456789" > strings/0x409/serialnumber echo "Renesas." > strings/0x409/manufacturer echo "Ethernet Gadget" > strings/0x409/product mkdir -p functions/ecm.usb0 mkdir -p configs/c.1 mkdir -p configs/c.1/strings/0x409 echo "ECM" > configs/c.1/strings/0x409/configuration if [ ! -L configs/c.1/ecm.usb0 ]; then ln -s functions/ecm.usb0 configs/c.1 fi echo 11e20000.usb > UDC echo 11e20000.usb > /sys/bus/platform/drivers/renesasusbhs/unbind The displayed trace is as follows: Internal error: synchronous external abort: 0000000096000010 [#1] SMP CPU: 0 UID: 0 PID: 188 Comm: sh Tainted: G M 6.17.0-rc7-next-20250922-00010-g41050493b2bd #55 PREEMPT Tainted: [M]=MACHINECHECK Hardware name: Renesas SMARC EVK version 2 based on r9a08g045s33 (DT) pstate: 604000c5 (nZCv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : usbhssysfunctionpullup+0x10/0x40 [renesasusbhs] lr : usbhsgupdatepullup+0x3c/0x68 [renesasusbhs] sp : ffff8000838b3920 x29: ffff8000838b3920 x28: ffff00000d585780 x27: 0000000000000000 x26: 0000000000000000 x25: 0000000000000000 x24: ffff00000c3e3810 x23: ffff00000d5e5c80 x22: ffff00000d5e5d40 x21: 0000000000000000 x20: 0000000000000000 x19: ffff00000d5e5c80 x18: 0000000000000020 x17: 2e30303230316531 x16: 312d7968703a7968 x15: 3d454d414e5f4344 x14: 000000000000002c x13: 0000000000000000 x12: 0000000000000000 x11: ffff00000f358f38 x10: ffff00000f358db0 x9 : ffff00000b41f418 x8 : 0101010101010101 x7 : 7f7f7f7f7f7f7f7f x6 : fefefeff6364626d x5 : 8080808000000000 x4 : 000000004b5ccb9d x3 : 0000000000000000 x2 : 0000000000000000 x1 : ffff800083790000 x0 : ffff00000d5e5c80 Call trace: usbhssysfunctionpullup+0x10/0x40 [renesasusbhs] (P) usbhsgpullup+0x4c/0x7c [renesasusbhs] usbgadgetdisconnectlocked+0x48/0xd4 gadgetunbinddriver+0x44/0x114 deviceremove+0x4c/0x80 devicereleasedriverinternal+0x1c8/0x224 devicereleasedriver+0x18/0x24 busremovedevice+0xcc/0x10c devicedel+0x14c/0x404 usbdelgadget+0x88/0xc0 usbdelgadgetudc+0x18/0x30 usbhsmodgadgetremove+0x24/0x44 [renesasusbhs] usbhsmodremove+0x20/0x30 [renesasusbhs] usbhsremove+0x98/0xdc [renesasusbhs] platformremove+0x20/0x30 deviceremove+0x4c/0x80 devicereleasedriverinternal+0x1c8/0x224 devicedriverdetach+0x18/0x24 unbindstore+0xb4/0xb8 drvattrstore+0x24/0x38 sysfskfwrite+0x7c/0x94 kernfsfopwriteiter+0x128/0x1b8 vfswrite+0x2ac/0x350 ksyswrite+0x68/0xfc arm64syswrite+0x1c/0x28 invokesyscall+0x48/0x110 el0svccommon.constprop.0+0xc0/0xe0 doel0svc+0x1c/0x28 el0svc+0x34/0xf0 el0t64synchandler+0xa0/0xe4 el0t64sync+0x198/0x19c Code: 7100003f 1a9f07e1 531c6c22 f9400001 (79400021) ---[ end trace 0000000000000000 ]--- note: sh[188] exited with irqs disabled note: sh[188] exited with preemptcount 1 The issue occurs because usbhssysfunctionpullup(), which accesses the IP registers, is executed after the USBHS clocks have been disabled. The problem is reproducible on the Renesas RZ/G3S SoC starting with the addition of module stop in the clock enable/disable APIs. With module stop functionality enabled, a bus error is expected if a master accesses a module whose clock has been stopped and module stop activated. Disable the IP clocks at the end of remove.

Frequently Asked Questions

Which systems are realistically exposed to this issue?

The reported failure occurs on the Renesas RZ/G3S SoC using the renesas_usbhs driver. It requires a USB ECM gadget to be configured through configfs and bound to the 11e20000.usb UDC.

What action triggers the failure?

The synchronous external abort is triggered when the renesas_usbhs driver is unbound after completing the described USB gadget configuration sequence. The provided reproduction performs the unbind by writing 11e20000.usb to /sys/bus/platform/drivers/renesas_usbhs/unbind.

Does this affect a default Ubuntu installation?

The provided information only demonstrates the issue after manually loading USB gadget modules, creating a configfs gadget, configuring an ECM function, binding it to the UDC, and then unbinding the driver. It does not state that this configuration is enabled by default.
