CVE-2025-38582: RDMA/hns: Fix double destruction of rsv_qp

HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 067ca15be8b8342931536b66206c496e76864ecf, 10b083dbba22be19baa848432b6f25aa68ab2db5, 5a791715803304bf81ae2a3a278f606e36b82481.

Low priority for now. Upgrade to Linux Linux 067ca15be8b8342931536b66206c496e76864ecf, 10b083dbba22be19baa848432b6f25aa68ab2db5, 5a791715803304bf81ae2a3a278f606e36b82481 or later.
