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...

The CMIS FW update code reads start_cmd_payload_size from the module FW Management Features CDB reply and uses it directly as the byte count for memcpy, writing into a destination buffer of 112 bytes (ETHTOOL_CMIS_CDB_LPL_...

CVE-2026-63987

Summary: CVE-2026-63987 affects the Linux kernel’s ethtool/ethnl path. The issue arises in ethnl_update_profile(): it iterates a nested Netlink list with index i and writes new_profile[i++] without bounding i. The destination is kmemdup()’d at NET_DIM_PARAMS_NUM_PROFILES entries (5), while Netlin...

CVE-2026-63986

CVE-2026-63986 concerns the Linux kernel ethtool tsinfo handling. When ethnl_tsinfo_prepare_dump() fails, the code path incorrectly calls genlmsg_cancel(skb, ehdr) via a goto err, even though no genlmsg was started, risking a crash by passing an error pointer to genlmsg_cancel. The connected reco...
