What it is

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

RDMA/erdma: complete object teardown when the destroy command fails

erdma_destroy_qp(), erdma_destroy_cq(), erdma_dereg_mr(), and

erdma_destroy_ah() returned early when erdma_post_cmd_wait() failed,

leaking the queue buffers, MTTs, doorbells and the STAG, QPN, CQN and AHN

identifiers. A command timeout clears ERDMA_CMDQ_STATE_OK_BIT and

permanently disables the command queue, so no retry can succeed; the RDMA

core keeps the object after a failed destructor and forced uverbs cleanup

then nulls the pointers, making the resources unreachable.

Warn on failure but release every software-owned resource and return

success, since during terminal destruction the hardware command result is

only diagnostic.
