Vulnerability identifier: #VU150851

CSH Severity: Medium

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-93151

CWE-ID: CWE-401

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause a memory leak.

The vulnerability exists due to failure to release response resources in the nvmet-rdma queue teardown routine when an RDMA connection is forcefully disconnected while I/O operations are in flight. A remote attacker can disconnect an RDMA connection while I/O operations are in flight to cause a memory leak.
