This handling is only\nneeded for iWARP to avoid having connections established while the link is\ndown or having connections remain functional after the IP address is\nremoved.\n\n  BUG: sleeping function called from invalid context at kernel/locking/mutex.\n  Call Trace:\n  kernel: dump_stack+0x66/0x90\n  kernel: ___might_sleep.cold.92+0x8d/0x9a\n  kernel: mutex_lock+0x1c/0x40\n  kernel: irdma_cm_teardown_connections+0x28e/0x4d0 [irdma]\n  kernel: ? check_preempt_curr+0x7a/0x90\n  kernel: ? select_idle_sibling+0x22/0x3c0\n  kernel: ? select_task_rq_fair+0x94c/0xc90\n  kernel: ? irdma_exec_cqp_cmd+0xc27/0x17c0 [irdma]\n  kernel: ? __wake_up_common+0x7a/0x190\n  kernel: irdma_if_notify+0x3cc/0x450 [irdma]\n  kernel: ? sched_clock_cpu+0xc/0xb0\n  kernel: irdma_inet6addr_event+0xc6/0x150 [irdma]","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-667"],"references":["https://git.kernel.org/stable/c/2cae7e519032e4b4672cb9204d5586a441924364","https://git.kernel.org/stable/c/a4c5115140ed1833197bad9a6b80265840ff427f","https://git.kernel.org/stable/c/cc0315564d6eec91c716d314b743321be24c70b3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49606","score":0.00196,"percentile":0.09342,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
