In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix memory leak of bonding resources
In a corner case of concurrent driver removal and driver reset, bonding resource is first released in hnsrocehwv2exit() during driver removal, and then is allocated again in hnsroceregister_device() during driver reset. This leads to memory leak because the release timing has already passed. This may also lead to a kernel panic as below because of the leaked notifier callback:
Call trace: 0xffffa20fccc04978 (P) rawnotifiercallchain+0x20/0x38 callnetdevicenotifiersinfo+0x60/0xb8 netdevlowerstate_changed+0x4c/0xb8
As Sashiko suggested, the teardown order of bonding resources should be inverted to make sure the resources are released when the driver is removed.
