Google: sys-kernel/csql-kernel-6_1: security update to 18244.582.11

high Tenable Cloud Security Plugin ID 451212

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: nvme-tcp: fix NULL pointer
dereferences in nvmet_tcp_build_pdu_iovec Commit efa56305908b ("nvmet-tcp: Fix a kernel panic when host
sends an invalid H2C PDU length") added ttag bounds checking and data_offset validation in
nvmet_tcp_handle_h2c_data_pdu(), but it did not validate whether the command's data structures
(cmd->req.sg and cmd->iov) have been properly initialized before processing H2C_DATA PDUs. The
nvmet_tcp_build_pdu_iovec() function dereferences these pointers without NULL checks. This can be
triggered by sending H2C_DATA PDU immediately after the ICREQ/ICRESP handshake, before sending a CONNECT
command or NVMe write command. Attack vectors that trigger NULL pointer dereferences: 1. H2C_DATA PDU sent
before CONNECT → both pointers NULL 2. H2C_DATA PDU for READ command → cmd->req.sg allocated, cmd->iov
NULL 3. H2C_DATA PDU for uninitialized command slot → both pointers NULL The fix validates both
cmd->req.sg and cmd->iov before calling nvmet_tcp_build_pdu_iovec(). Both checks are required because: -
Uninitialized commands: both NULL - READ commands: cmd->req.sg allocated, cmd->iov NULL - WRITE commands:
both allocated (CVE-2026-22998)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.582.11 or later.
