What it actually does
Race condition between rpmsg_ctrldev release and cdev managed object cleanup leads to premature kfree of rpmsg_ctrldev while cdev timer or other state remains active, manifesting as use-after-free or debugobject warnings during kobject_delayed_cleanup.
Why it matters to the business
Kernel instability or crashes on systems using rpmsg character devices, particularly embedded or Android-based platforms; widespread kernel exposure increases operational risk but low EPSS indicates limited real-world exploitation to date.
How an attack unfolds
An attacker triggers concurrent device open/close or removal operations on rpmsg_ctrldev instances to win the race between rpmsg_ctrldev_release_device and cdev release, resulting in slab free of an object still referenced by delayed work or timers; the provided backtrace shows the resulting ODEBUG warning in debugobjects.c.
How to fix it
Update affected Linux kernels to the commit 74d85e9fbc7022a4011102c7474a9c7aeb704a35 or later that replaces cdev add/del with the cdev_device_add/del API; apply vendor kernel updates containing this fix.
How to confirm the fix worked
Confirm kernel source contains the cdev_device_add/del usage in rpmsg char driver or verify the fixed commit hash is present; test device removal under load to ensure no ODEBUG warnings for timer_list objects occur.
Typical attack path
- Obtain local access or sufficient privileges to interact with /dev/rpmsg_ctrl* nodes
- Rapidly open and close or remove rpmsg character devices to induce concurrent release paths
- Trigger kobject_delayed_cleanup workqueue item while cdev state remains active
- Observe or exploit resulting slab corruption or use-after-free during kfree in rpmsg_ctrldev_release_device
How to detect it
Search kernel logs and dmesg for strings matching the ODEBUG warning, debug_print_object, rpmsg_ctrldev_release_device, or kobject_delayed_cleanup call traces; inspect slab free paths involving rpmsg_ctrldev structs.
- rpmsg_ctrldev_release_device
- debug_print_object+0x13c/0x1b0
- ODEBUG: free active (active state 0) object type: timer_list
- kobject_delayed_cleanup
- slab_free_freelist_hook.*rpmsg
What your security team should do
- Prioritize kernel upgrades to the referenced fixed commit across all affected distributions and embedded devices
- Monitor kernel logs for debugobject warnings referencing rpmsg_ctrldev_release_device or delayed_work_timer_fn
- Restrict unprivileged access to rpmsg character devices where feasible until patches are deployed
The record
In the Linux kernel, the following vulnerability has been resolved: rpmsg: char: Fix race between the release of rpmsg_ctrldev and cdev struct rpmsg_ctrldev contains a struct cdev. The current code frees the rpmsg_ctrldev struct in rpmsg_ctrldev_release_device(), but the cdev is a managed object, therefore its release is not predictable and the rpmsg_ctrldev could be freed before the cdev is entirely released, as in the backtrace below.
