critical Tenable Cloud Security Plugin ID 467362

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-auth: validate reply message
 payload bounds against transfer length nvmet_auth_reply() accesses the variable-length rval[] array using
 attacker-controlled hl (hash length) and dhvlen (DH value length) fields without verifying they fit within
 the allocated buffer of tl bytes. A malicious NVMe-oF initiator can craft a DHCHAP_REPLY message with a
 small transfer length but large hl/dhvlen values, causing out-of-bounds heap reads when the target
 processes the DH public key (rval + 2*hl) or performs the host response memcmp. With DH authentication
 configured, the OOB pointer is passed directly to sg_init_one() and read by
 crypto_kpp_compute_shared_secret(), reaching up to 526 bytes past the buffer. This is exploitable pre-
 authentication. Add bounds validation ensuring sizeof(*data) + 2*hl + dhvlen <= tl before any access to
 the variable-length fields. Discovered by Atuin - Automated Vulnerability Discovery Engine.
 (CVE-2026-64319)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.58 or later.
