CVE-2024-49569
Estado: ModificadaMedia (5.7)—
In the Linux kernel, the following vulnerability has been resolved:
nvme-rdma: unquiesce admin_q before destroy it
Kernel will hang on destroy admin_q while we create ctrl failed, such as following calltrace:
This due to we have quiesced admi_q before cancel requests, but forgot to unquiesce before destroy it, as a result we fail to drain the pending requests, and hang on blk_mq_freeze_queue_wait() forever. Here try to reuse nvme_rdma_teardown_admin_queue() to fix this issue and simplify the code.
