Hello: This patch was applied to netdev/net.git (main) by Jakub Kicinski [off-list ref]: On Tue, 24 Mar 2026 00:57:30 +0800 you wrote:
If auxiliary_device_add() fails, add_adev() jumps to add_fail and calls auxiliary_device_uninit(adev). The auxiliary device has its release callback set to adev_release(), which frees the containing struct mana_adev. Since adev is embedded in struct mana_adev, the subsequent fall-through to init_fail and access to adev->id may result in a use-after-free. [...]
Here is the summary with links:
