Schedule a fix SSVC: Track

A bug in how the Linux kernel cleans up a storage driver on certain systems can crash the whole machine when that driver is removed.

What it actually does

Use-after-free in sata_fsl driver: sata_fsl_remove performs iounmap and kfree on host_priv before ata_host_stop invokes sata_fsl_port_stop which still dereferences the unmapped hcr_base via ioread32.

Why it matters to the business

Kernel panic and system reboot when the sata_fsl module is unloaded on affected PowerPC systems, disrupting storage operations and availability.

How an attack unfolds

An attacker with local privileges executes rmmod sata_fsl, triggering the driver's remove routine that frees resources prematurely; subsequent port_stop callback in the libata teardown path then accesses the freed mapping, causing an oops.

How to fix it

Apply the upstream fix that moves iounmap/kfree into a new sata_fsl_host_stop callback bound to host_stop; update to a kernel containing the resolution for this driver ordering bug.

How to confirm the fix worked

Confirm the presence of sata_fsl_host_stop and its assignment to host_stop in the driver; verify that iounmap and kfree no longer occur inside sata_fsl_remove; test module load/unload cycle on target hardware.

Typical attack path

  1. Obtain local shell on PPC64 Linux system using sata_fsl
  2. Execute rmmod sata_fsl.ko or equivalent module unload
  3. Driver remove path calls iounmap and kfree on host_priv
  4. libata teardown later invokes port_stop which reads from unmapped address
  5. Kernel oops and potential crash

How to detect it

Review kernel logs for oops signatures containing ioread32 in sata_fsl_port_stop, free_irq followed by ata_host_stop, and references to sata_fsl_remove during module unload; correlate with audit logs showing rmmod of sata_fsl.

What your security team should do

  • Prioritize kernel update on all PowerPC systems that may load sata_fsl
  • Restrict local module unload privileges via modprobe blacklist or capabilities where feasible
  • Monitor for unexpected sata_fsl module removal in production environments

The record

In the Linux kernel, the following vulnerability has been resolved: sata_fsl: fix UAF in sata_fsl_port_stop when rmmod sata_fsl When the `rmmod sata_fsl.ko` command is executed in the PPC64 GNU/Linux, a bug is reported: ================================================================== BUG: Unable to handle kernel data access on read at 0x80000800805b502c Oops: Kernel access of bad area, sig: 11 [#1] NIP [c0000000000388a4] .ioread32+0x4/0x20 LR [80000000000c6034] .sata_fsl_port_stop+0x44/0xe0 [sata_fsl] Call Trace: .free_irq+0x1c/0x4e0 (unreliable) .ata_host_stop+0x74/0xd0 [libata] .release_nodes+0x330/0x3f0 .device_release_driver_internal+0x178/0x2c0 .driver_detach+0x64/0xd0 .bus_remove_driver+0x70/0xf0 .driver_unregister+0x38/0x80 .platform_driver_unregister+0x14/0x30 .fsl_sata_driver_exit+0x18/0xa20 [sata_fsl] .__se_sys_delete_module+0x1ec/0x2d0 .system_call_exception+0xfc/0x1f0 system_call_common+0xf8/0x200 ================================================================== The triggering of the BUG is shown in the following stack: driver_detach device_release_driver_internal __device_release_driver drv->remove(dev) --> platform_drv_remove/platform_remove drv->remove(dev) --> sata_fsl_remove iounmap(host_priv->hcr_base); <---- unmap kfree(host_priv); <---- free devres_release_all release_nodes dr->node.release(dev, dr->data) --> ata_host_stop ap->ops->port_stop(ap) --> sata_fsl_port_stop ioread32(hcr_base + HCONTROL) <---- UAF host->ops->host_stop(host) The iounmap(host_priv->hcr_base) and kfree(host_priv) functions should not be executed in drv->remove. These functions should be executed in host_stop after port_stop. Therefore, we move these functions to the new function sata_fsl_host_stop and bind the new function to host_stop.
