What it actually does

Incorrect flexspi compatible string on imx8ulp causes the nxp_fspi driver to assume 32 LUTs instead of the actual 16, triggering a warning and potential failure in nxp_fspi_exec_op during spi_nor_probe and device initialization.

Why it matters to the business

Systems using affected older Ubuntu kernels on NXP i.MX8ULP hardware may fail to boot or experience flash memory access errors, leading to operational downtime on embedded devices; the issue has been public for over 690 days with low exploitation probability and no ransomware use.

How an attack unfolds

An attacker with local access or the ability to influence boot-time SPI NOR probing on an unpatched imx8ulp system triggers the misconfigured driver path, resulting in a kernel warning and potential denial of service during device attachment; no specific named threat actors have been linked to this exact misconfiguration beyond general Linux kernel exploitation campaigns.

How to fix it

Upgrade to fixed kernel versions including linux 3.13.0-74.118, 4.4.0-2.16, 4.4.0-1001.10, 4.4.0-1003.4, 4.8.0-36.36~16.04.1, 3.16.0-57.77~14.04.1, 3.19.0-42.48~14.04.1, or 4.2.0-22.27~14.04.1 depending on the specific Ubuntu package and release.

How to confirm the fix worked

Boot the system and confirm absence of the nxp_fspi_exec_op warning at drivers/spi/spi-nxp-fspi.c:855; verify device tree uses the corrected imx8ulp flexspi compatible string and that spi_nor_scan completes without error.

Typical attack path

  1. Identify vulnerable imx8ulp-based system running affected Ubuntu kernel
  2. Trigger spi_nor_probe via boot or SPI device registration
  3. Cause nxp_fspi_exec_op to execute with incorrect LUT assumptions
  4. Observe kernel warning and potential probe failure

How to detect it

Search kernel boot logs and dmesg for the exact warning string referencing nxp_fspi_exec_op+0xb04/0xb64 and spi-nxp-fspi.c:855 on affected hardware; check for failed spi_nor_probe or device attachment during early init.

  • nxp_fspi_exec_op+0xb04/0xb64
  • WARNING: CPU: 0 PID: 1 at drivers/spi/spi-nxp-fspi.c:855
  • spi_nor_read_id+0x80/0xcc
  • Hardware name: NXP i.MX8ULP EVK (DT)

What your security team should do

  • Prioritize kernel upgrades on all imx8ulp Ubuntu systems to the listed fixed versions
  • Monitor boot logs for the specific WARNING message during device probe
  • Test SPI NOR functionality post-upgrade on representative hardware

The record

In the Linux kernel, the following vulnerability has been resolved: arm64: dts: imx8ulp: correct the flexspi compatible string The flexspi on imx8ulp only has 16 LUTs, and imx8mm flexspi has 32 LUTs, so correct the compatible string here, otherwise will meet below error: [ 1.119072] ------------[ cut here ]------------ [ 1.123926] WARNING: CPU: 0 PID: 1 at drivers/spi/spi-nxp-fspi.c:855 nxp_fspi_exec_op+0xb04/0xb64 [ 1.133239] Modules linked in: [ 1.136448] CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.11.0-rc6-next-20240902-00001-g131bf9439dd9 #69 [ 1.146821] Hardware name: NXP i.MX8ULP EVK (DT) [ 1.151647] pstate: 40000005 (nZcv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 1.158931] pc : nxp_fspi_exec_op+0xb04/0xb64 [ 1.163496] lr : nxp_fspi_exec_op+0xa34/0xb64 [ 1.168060] sp : ffff80008002b2a0 [ 1.171526] x29: ffff80008002b2d0 x28: 0000000000000000 x27: 0000000000000000 [ 1.179002] x26: ffff2eb645542580 x25: ffff800080610014 x24: ffff800080610000 [ 1.186480] x23: ffff2eb645548080 x22: 0000000000000006 x21: ffff2eb6455425e0 [ 1.193956] x20: 0000000000000000 x19: ffff80008002b5e0 x18: ffffffffffffffff [ 1.201432] x17: ffff2eb644467508 x16: 0000000000000138 x15: 0000000000000002 [ 1.208907] x14: 0000000000000000 x13: ffff2eb6400d8080 x12: 00000000ffffff00 [ 1.216378] x11: 0000000000000000 x10: ffff2eb6400d8080 x9 : ffff2eb697adca80 [ 1.223850] x8 : ffff2eb697ad3cc0 x7 : 0000000100000000 x6 : 0000000000000001 [ 1.231324] x5 : 0000000000000000 x4 : 0000000000000000 x3 : 00000000000007a6 [ 1.238795] x2 : 0000000000000000 x1 : 00000000000001ce x0 : 00000000ffffff92 [ 1.246267] Call trace: [ 1.248824] nxp_fspi_exec_op+0xb04/0xb64 [ 1.253031] spi_mem_exec_op+0x3a0/0x430 [ 1.257139] spi_nor_read_id+0x80/0xcc [ 1.261065] spi_nor_scan+0x1ec/0xf10 [ 1.264901] spi_nor_probe+0x108/0x2fc [ 1.268828] spi_mem_probe+0x6c/0xbc [ 1.272574] spi_probe+0x84/0xe4 [ 1.275958] really_probe+0xbc/0x29c [ 1.279713] __driver_probe_device+0x78/0x12c [ 1.284277] driver_probe_device+0xd8/0x15c [ 1.288660] __device_attach_driver+0xb8/0x134 [ 1.293316] bus_for_each_drv+0x88/0xe8 [ 1.297337] __device_attach+0xa0/0x190 [ 1.301353] device_initial_probe+0x14/0x20 [ 1.305734] bus_probe_device+0xac/0xb0 [ 1.309752] device_add+0x5d0/0x790 [ 1.313408] __spi_add_device+0x134/0x204 [ 1.317606] of_register_spi_device+0x3b4/0x590 [ 1.322348] spi_register_controller+0x47c/0x754 [ 1.327181] devm_spi_register_controller+0x4c/0xa4 [ 1.332289] nxp_fspi_probe+0x1cc/0x2b0 [ 1.336307] platform_probe+0x68/0xc4 [ 1.340145] really_probe+0xbc/0x29c [ 1.343893] __driver_probe_device+0x78/0x12c [ 1.348457] driver_probe_device+0xd8/0x15c [ 1.352838] __driver_attach+0x90/0x19c [ 1.356857] bus_for_each_dev+0x7c/0xdc [ 1.360877] driver_attach+0x24/0x30 [ 1.364624] bus_add_driver+0xe4/0x208 [ 1.368552] driver_register+0x5c/0x124 [ 1.372573] __platform_driver_register+0x28/0x34 [ 1.377497] nxp_fspi_driver_init+0x1c/0x28 [ 1.381888] do_one_initcall+0x80/0x1c8 [ 1.385908] kernel_init_freeable+0x1c4/0x28c [ 1.390472] kernel_init+0x20/0x1d8 [ 1.394138] ret_from_fork+0x10/0x20 [ 1.397885] ---[ end trace 0000000000000000 ]--- [ 1.407908] ------------[ cut here ]------------
