high Tenable Self-Hosted Container Security Plugin ID 469907

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: ethtool: cmis: validate
 start_cmd_payload_size from module The CMIS firmware update code reads start_cmd_payload_size from the
 module's FW Management Features CDB reply and uses it directly as the byte count for memcpy. The
 destination buffer is 112 bytes (ETHTOOL_CMIS_CDB_LPL_MAX_PL_LENGTH - 8). So a malicious module (or
 corrupted response) can cause a OOB write later on in cmis_fw_update_start_download(). Let's error out. If
 modules that expect longer LPL writes actually exist we should revisit. struct
 cmis_cdb_start_fw_download_pl's definition has to move, no change there. (CVE-2026-63995)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.3 or later.
