CVE-2026-63996

In the Linux kernel, the following vulnerability has been resolved: ethtool: cmis: require exact CDB reply length Malicious SFP module could respond with rpllen longer than what cmiscdbprocessreply expected, leading to OOB writes. Malicious HW is a bit theoretical but some modules may just be bug...

CVE-2026-63995

In the Linux kernel, the following vulnerability has been resolved: ethtool: cmis: validate startcmdpayloadsize from module The CMIS firmware update code reads startcmdpayloadsize from the module's FW Management Features CDB reply and uses it directly as the byte count for memcpy. The destination...

CVE-2026-63996

CVE-2026-63996 concerns the Linux kernel ethtool cmis path. The issue arises when a malicious SFP module responds with a reply length longer than what cmis_cdb_process_reply() expects, potentially causing out-of-bounds writes. The fix involves strengthening the existing length checks to also guar...

Linux Distros Unpatched Vulnerability : CVE-2025-37791

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: ethtool: cmiscdb: use correct rpl size in ethtoolcmismodulepoll rpl is passed as a pointer t...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ethtool: cmiscdb: Use the correct rpl size in ethtoolcmismodulepoll. rpl is passed as a pointer to ethtoolcmismodulepoll. Therefore, the correct size of rpl is sizeofrpl, which should be just 1 byte. Using the pointer’s actual si...

DEBIAN-CVE-2025-37791

In the Linux kernel, the following vulnerability has been resolved: ethtool: cmiscdb: use correct rpl size in ethtoolcmismodulepoll rpl is passed as a pointer to ethtoolcmismodulepoll, so the correct size of rpl is sizeofrpl which should be just 1 byte. Using the pointer size instead can cause...
