{"id":"AZL-106173","summary":"CVE-2026-98352 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/rtrs-clt: Fix CQ pool leak when connect is interrupted\n\nThe client borrows shared CQ credits in the ADDR_RESOLVED handler via\nib_cq_pool_get(), before the peer is connected. create_cm() can return\n-ERESTARTSYS from wait_event_interruptible_timeout() without destroying\nthe CM ID. The init_conns() and stop-and-destroy paths then call\ndestroy_con_cq_qp() while cq is still NULL (no PUT) and only afterwards\nrdma_destroy_id().\n\nCMA serializes the handler against rdma_destroy_id() with handler_mutex,\nbut that does not order the GET against destroy_con_cq_qp(). If\nADDR_RESOLVED has already passed the DESTROYING check, it can take\ncon_mutex, GET credits, and then lose the con to kfree. Device\nunregister later hits WARN_ON(cq-\u003ecqe_used) in ib_cq_pool_cleanup().\n\nSet a per-connection flag under con_mutex before CQ/QP teardown so a\nracing ADDR_RESOLVED cannot borrow credits after teardown has begun.","modified":"2026-10-07T14:16:57.683820450Z","published":"2026-10-06T09:18:28Z","upstream":["CVE-2026-98352"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98352"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-106173.json"}}],"schema_version":"1.9.0"}
