Vulnerability from github – Published: 2026-06-26 21:32 – Updated: 2026-07-08 06:31

Details

In the Linux kernel, the following vulnerability has been resolved:

idpf: fix double free and use-after-free in aux device error paths

When auxiliary_device_add() fails in idpf_plug_vport_aux_dev() or idpf_plug_core_aux_dev(), the err_aux_dev_add label calls auxiliary_device_uninit() and falls through to err_aux_dev_init. The uninit call will trigger put_device(), which invokes the release callback (idpf_vport_adev_release / idpf_core_adev_release) that frees iadev. The fall-through then reads adev->id from the freed iadev for ida_free() and double-frees iadev with kfree().

Free the IDA slot and clear the back-pointer before uninit, while adev is still valid, then return immediately.

Commit 65637c3a1811 ("idpf: fix UAF in RDMA core aux dev deinitialization") fixed the same use-after-free in the matching unplug path in this file but missed both probe error paths.

Severity

7.8 (High)
