critical Tenable Cloud Security Plugin ID 466037

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: check INIT_FAILED before
 nvmet_req_uninit in digest error path In nvmet_tcp_try_recv_ddgst(), when a data digest mismatch is
 detected, nvmet_req_uninit() is called unconditionally. However, if the command arrived via the
 nvmet_tcp_handle_req_failure() path, nvmet_req_init() had returned false and percpu_ref_tryget_live() was
 never executed. The unconditional percpu_ref_put() inside nvmet_req_uninit() then causes a refcount
 underflow, leading to a WARNING in percpu_ref_switch_to_atomic_rcu, a use-after-free diagnostic, and
 eventually a permanent workqueue deadlock. Check cmd->flags & NVMET_TCP_F_INIT_FAILED before calling
 nvmet_req_uninit(), matching the existing pattern in nvmet_tcp_execute_request(). (CVE-2026-64534)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.37 or later.
