What it actually does
Use-after-free in vector_device_release when drvdata is accessed after the device is no longer valid, leading to kernel panic on removal of a vector device.
Why it matters to the business
Unexpected system crashes and kernel panics during device removal operations can cause downtime and loss of availability on affected Linux systems; low exploitation likelihood limits widespread impact.
How an attack unfolds
An attacker with local access triggers vector device removal through mconsole or platform device unregistration paths, causing the release handler to dereference stale drvdata and crash the kernel.
How to fix it
Update to a kernel containing the fix that replaces drvdata access with container_of() in vector_device_release; apply the corrected package versions for any affected distributions.
How to confirm the fix worked
Confirm the presence of the container_of() change in the vector release function and test device removal without triggering a panic or segfault in the release path.
Typical attack path
- Obtain local access to a system running an affected kernel version
- Trigger vector device addition and subsequent removal via mconsole or platform APIs
- Force the release callback to execute with invalid drvdata
- Induce kernel panic via the resulting memory access violation
How to detect it
Review kernel logs for vector_device_release crashes, segfaults during device_release, and kworker or mconsole activity preceding panics; correlate with platform_device_unregister calls.
What your security team should do
- Prioritize kernel updates on systems exposing vector devices
- Monitor for device removal events in logs
- Restrict local access to limit attack surface
The record
In the Linux kernel, the following vulnerability has been resolved: um: vector: Do not use drvdata in release The drvdata is not available in release. Let's just use container_of() to get the vector_device instance. Otherwise, removing a vector device will result in a crash: RIP: 0033:vector_device_release+0xf/0x50 RSP: 00000000e187bc40 EFLAGS: 00010202 RAX: 0000000060028f61 RBX: 00000000600f1baf RCX: 00000000620074e0 RDX: 000000006220b9c0 RSI: 0000000060551c80 RDI: 0000000000000000 RBP: 00000000e187bc50 R08: 00000000603ad594 R09: 00000000e187bb70 R10: 000000000000135a R11: 00000000603ad422 R12: 00000000623ae028 R13: 000000006287a200 R14: 0000000062006d30 R15: 00000000623700b6 Kernel panic - not syncing: Segfault with no mm CPU: 0 UID: 0 PID: 16 Comm: kworker/0:1 Not tainted 6.12.0-rc6-g59b723cd2adb #1 Workqueue: events mc_work_proc Stack: 60028f61 623ae028 e187bc80 60276fcd 6220b9c0 603f5820 623ae028 00000000 e187bcb0 603a2bcd 623ae000 62370010 Call Trace: [<60028f61>] ? vector_device_release+0x0/0x50 [<60276fcd>] device_release+0x70/0xba [<603a2bcd>] kobject_put+0xba/0xe7 [<60277265>] put_device+0x19/0x1c [<60281266>] platform_device_put+0x26/0x29 [<60281e5f>] platform_device_unregister+0x2c/0x2e [<60029422>] vector_remove+0x52/0x58 [<60031316>] ? mconsole_reply+0x0/0x50 [<600310c8>] mconsole_remove+0x160/0x1cc [<603b19f4>] ? strlen+0x0/0x15 [<60066611>] ? __dequeue_entity+0x1a9/0x206 [<600666a7>] ? set_next_entity+0x39/0x63 [<6006666e>] ? set_next_entity+0x0/0x63 [<60038fa6>] ? um_set_signals+0x0/0x43 [<6003070c>] mc_work_proc+0x77/0x91 [<60057664>] process_scheduled_works+0x1b3/0x2dd [<60055f32>] ? assign_work+0x0/0x58 [<60057f0a>] worker_thread+0x1e9/0x293 [<6005406f>] ? set_pf_worker+0x0/0x64 [<6005d65d>] ? arch_local_irq_save+0x0/0x2d [<6005d748>] ? kthread_exit+0x0/0x3a [<60057d21>] ? worker_thread+0x0/0x293 [<6005dbf1>] kthread+0x126/0x12b [<600219c5>] new_thread_handler+0x85/0xb6
