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...
CVE-2026-63996 ethtool: cmis: require exact CDB reply length
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 ethtool: cmis: validate start_cmd_payload_size from module
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-2026-63995
CVE-2026-63995 affects the Linux kernel ethtool CMIS firmware update path. 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-2026-63992 tunnels: do not assume transport header in iptunnel_pmtud_check_icmp()
In the Linux kernel, the following vulnerability has been resolved: tunnels: do not assume transport header in iptunnelpmtudcheckicmp In some cases, iptunnelpmtudcheckicmp can be called while skb transport header is not set. This triggers an out-of-bound access, because typeofskb-transportheader0...

In the Linux kernel, the following vulnerability has been resolved: USB: serial: safeserial: fix memory corruption with small endpoint Make sure that the bulk-out buffer size is at least eight bytes to avoid user-controlled slab corruption in "safe" mode should a malicious device report a smaller...
CVE-2026-63957
The CVE-2026-63957 issue affects the Linux kernel USB serial safe_serial implementation. The vulnerability is a memory corruption risk when using a small endpoint, arising from an inadequately sized bulk-out buffer; in safe mode, a malicious device reporting a smaller size could lead to user-cont...
