No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.
In the Linux kernel, the following vulnerability has been resolved:
RDMA/erdma: Hold QP references for AE and CM processing
AE QP fatal events and iWARP CM paths load QPs from dev->qp_xa
and then use or reference them outside the xarray lock.
erdma_destroy_qp() can drop the destroy-path reference and free QP
resources while such a lookup is in flight.
Add erdma_qp_get_by_qpn() to acquire a kref under the xarray
lock with kref_get_unless_zero(). Remove the QP from the xarray
before dropping the destroy-path reference so no new lookup can acquire
it while destruction waits for existing users.
CISA SSVCTrack at low or medium mission impact; Track or Attend at high (mission-essential systems).
No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.
Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
